Glen Johnson is believed to have been sent home from England Under-21 duty after angering manager Peter Taylor. The Football Association's official line is that Johnson had a thigh injury which forced him out of Tuesday's European Championship qualifier.
But Chelsea's 21-year-old right-back is understood to have angered Taylor and fellow team-mates with poor time-keeping and his poor attitude.
However a Chelsea statement said: "Glen has come back with a thigh strain."
Johnson had played in Friday's U21 4-0 success over Wales at Wrexham.
The player's action could have serious repercussions on his hopes of breaking back into the England first-team after being dropped following the 4-1 defeat to Denmark.
Taylor has already reported Johnson's behaviour to FA chiefs and Johnson's club boss Jose Mourinho.
