German star Boris Vukcevic remains in a coma with severe head injuries but his condition has improved enough for him to be moved to a rehabilitation clinic, his Bundesliga club Hoffenheim said.
The 22-year-old has been in a coma since his car hit an oncoming truck on September 28 at Bammental, near Heidelberg, but he was showing steady signs of improvement and was moved from Heidelberg University Hospital.
The German under-21 midfielder has already had two operations.
"We remain very confident that Boris will make a recovery, but the situation is still very tense, so we want to deal with this respectfully and sensitively," said Hoffenheim manager Andreas Mueller.
Vukcevic is a diabetic and he was hypoglycemic - suffering low blood sugar level - at the time of the accident, a medical report has revealed.
Local police are investigating the accident, which they say occurred when Vukcevic's car crossed into the lane of oncoming traffic.
Vukcevic has played for Hoffenheim since 2008 and made five appearances this season.
Hoffenheim claimed a vital 3-1 win against second-tier Kaiserslautern in the first leg of the Bundesliga play-off.
