London - Manu Tuilagi and Denny Solomona have been sent home from an England training camp due to "team culture issues", the Rugby Football Union announced on Monday.
"Denny Solomona and Manu Tuilagi have been sent home today from England's training camp following team culture issues," the RFU said in a short press release. "We will not be commenting further."
Britain's Press Association said the pair were disciplined for drinking alcohol during a three-day get-together in Teddington, southwest London.
Leicester centre Tuilagi, 26, was only recalled to the England fold last Thursday, a succession of injuries having prevented him from playing for his country since March 2016.
New Zealand-born Sale wing Solomona, 23, made his England bow during a two-Test tour of Argentina in June, crowning his debut with a late match-winning try in a 38-34 win in San Juan.
England head coach Eddie Jones had assembled a 37-man squad for the training camp, which was due to finish on Monday.
Jones spoke in glowing terms about Tuilagi last week, explaining that his display in England's 38-21 win over New Zealand in 2012 showed he was worth persevering with despite his injury problems.
"I've got no idea where he is really until we see him," Jones said.
"But I do know he can demolish the All Blacks, so he's worth time, he's worth effort and worth a lot of care. Manu's just got to get fit and healthy."
Tuilagi has a chequered disciplinary record, his misdemeanours including a conviction for assault and a five-week ban for punching England colleague Chris Ashton.
Jones spoke about the importance of discipline last week after being asked about Harlequins prop Kyle Sinckler, who was arrested after a night out during the British and Irish Lions' tour of New Zealand.
"It is not a black mark against him, but it will be if he does it again," Jones said of Sinckler's arrest.
"It's a good lesson to have and I think everyone will see that and learn from it. If they don't learn from it, they are in strife."
