In an interview in April 2012, Carroll admitted that he had gained a reputation for drinking and socialising during his time at Newcastle, but that since joining Liverpool in January 2011 he had "settled down" and changed his lifestyle.
Bilic is keen to protect a player he views as precious to the continuing development of West Ham and subbed the striker off minutes after his second goal.
The 27-year-old is believed to have picked up the injury after coming off the bench during West Ham's Europa League play-off round tie against Astra Giurgiu on Thursday night, and will miss the club's first league game at the Olympic Stadium against Bournemouth this afternoon.
Between 2010 and 2012, Carroll played nine games for England, scoring twice, including one goal at UEFA Euro 2012.
Carroll, hoping to force his way into the England picture under former boss Sam Allardyce this season, was a 63rd minute substitute in Romania.
Carroll received his first call up to the England under-21s on 5 August 2009. He made his debut on 11 August 2009 against the Netherlands, coming on as a second-half substitute. On his second cap with the under-21 team, on 9 October 2009 against Macedonia, he scored two goals and assisted another as England won 6–3.
"In a game where we didn't always have a big influence and he didn't have more service, he made his mark.
The growing injury list could force West Ham to make a number of late acquisitions in the transfer market, with forward pair Wilfried Bony and Lioc Remy being linked with loan moves to the club after seemingly being made surplus to requirements at Manchester City and Chelsea respectively.
The West Ham frontman last played for England in 2012 and has since struggled to force his way back into the national set-up following a string of injury lay-offs.
The injury is not thought to be long term, but it has left the club frustrated coming just days after new £20million signing Andre Ayew was ruled out for four months.

Left-back Aaron Cresswell (knee) will not be returning for another three months, while Manuel Lanzini (knee) and Sofiane Feghouli (hamstring) are also unavailable.
His latest setback adds to a growing casualty list for Bilic.
Premier League clubs had all been warned that there would be a crackdown this season on dissent. “You can’t take time to adjust,” said Howe. “You need to be very disciplined. You need to keep 11 men on the pitch. I have drilled it into them. I don’t know if I can do any more. It is something we can’t afford to do.”
West Ham's new surroundings may offer very different sightlines to those at the old Boleyn Ground but the image of Carroll soaring into the air like an NBA star is set to be revived at the London Stadium.
Carroll, who has played only 81 league games during more than four years at West Ham, has been ruled out for between four and six weeks. He wrote on Twitter that he was “devastated” about his latest injury - and claimed still to be the “15-20 goal man” – even if Bilic appears to be running out of patience.
He made his FA Cup debut on 17 January 2007, appearing as substitute for the last ten minutes in the 5–1 home defeat by Birmingham City. On 25 February 2007, Carroll made his Premier League debut for Newcastle, coming on as a substitute in the 87th minute in the 1–0 defeat by Wigan Athletic, almost scoring in the process; only a good save from Wigan goalkeeper John Filan prevented him from scoring his first Newcastle goal.
However, Carroll has revealed playing for England again remains a big ambition.
Carroll scored twice in the Hammers' final pre-season friendly against Juventus ahead of the new Premier League campaign, but it was not enough as the Serie A champions won 3-2 at the London Stadium.
Andrew Thomas "Andy" Carroll (born 6 January 1989) is an English professional footballer who plays as a striker for Premier League club West Ham United and the England national team. A strong and very physical centre-forward, Carroll is distinguished by his powerful aerial abilities, with West Ham manager Slaven Bilić claiming that he is "the best in the world at heading a football".
Hammers boss Slaven Bilic was similarly effusive, saying: "Andy made his mark again, he is that kind of a player and they were goals typical of his threat. He proved once more that we are right to count on him. If he plays like he did here, there are not too many players who can do what he did."
The news will come as a disappointment for Carroll who had been touted for a call-up to Sam Allardyce's first England squad for the World Cup qualifier fixture against Slovakia next month.
“I will sign now the contract if his injury is four weeks or six weeks and, after that, good until the end of the season,” he said. “I will take it. Andy is Andy. He’s dedicated now to training, to everything, it’s a big blow for us, a big question mark also and big frustration with these things that are happening to him. The worst situation is when you plan, then you can’t count on him. All the time.”
West Ham manager Slaven Bilic has admitted that Andy Carroll’s latest knee injury raises a “big question mark” and that he no longer feels like he can count on the former England striker.

On 21 May 2013, West Ham and Liverpool agreed a fee of around £15 million to make the loan move permanent, pending Carroll agreeing to the move, and then to personal terms. Carroll signed a six-year contract with West Ham on 19 June 2013 for a club record transfer fee of £15 million.
Boss Slaven Bilic is said to be regretting his decision to bring Carroll on against Astra instead of giving young Ashley Fletcher some game time.

West Ham had hoped Carroll was over the injury nightmare that wreaked havoc on their ambitions and his own campaign last season.
The 27-year-old marksman is understood to have picked up the problem after making a substitute appearance in Thursday night’s Europa League game against Astra Giurgiu.
Mehdi Benatia, a central defender who in his Roma days was widely hailed as Serie A's best and is now at Juve on loan from Bayern Munich, was given the type of bruising many Premier League defenders have suffered down the years.
Sam Allardyce's appointment as the new England manager last month has led to speculation Carroll could be included in his first squad for the 2018 World Cup qualifier against Slovakia on September 4.

On 14 August 2007, Carroll began a six-month loan with Preston North End, and made his debut for them in the League Cup against Morecambe on the same day. Carroll was sent off playing for Preston against Scunthorpe United on 18 September. He scored his first Championship goal, and his first English league goal, against Leicester City on 6 November.
"My missus got on my case," he added. "I had to listen to her. Obviously it's worked. There a lot of people who have tried to drill it into my head for three or four years now and I haven't really listened.
The 27-year-old was injured during Thursday's 1-1 draw away to Romanian champions Astra Giurgiu in their Europa League play-off first leg.
Aaron Cresswell, Sofiane Feghouli and Manuel Lanzini are also out injured, while midfielder Dimitri Payet is still regaining full fitness, having been given a break after helping France reach the final at Euro 2016 in July.
The forward, who has played nine times for England, has spent about half of his time at the club out injured.
West Ham United's £20.5 million signing of Andre Ayew from Swansea City on Monday evening continued the summer reorganisation of their forward line. Diafra Sakho's transfer to West Brom collapsed last week after a failed medical, while Enner Valencia is now linked with a move to the Hawthorns. Change is occurring at the Hammers in more ways than their move to the London Stadium.
"I just have to listen to people and take it easy."
Bilic described Carroll as “so down” and said that the frustration was compounded by how well he had performed through pre-season. As well as Carroll, West Ham were on Sunday missing Dimitri Payet, Aaron Cresswell, Manuel Lanzini, Sofiane Feghouli and Andre Ayew. Payet and Ayew should both be back within the next week. “
