Deceuninck-QuickStep rider Fabio Jakobsen remains in a serious but stable condition after undergoing facial surgery following a horrific crash during the Tour of Poland.
Jakobsen was placed in an induced coma after being airlifted to Wojewodzki Szpital in Katowice on Wednesday following the smash at the end of stage one.
Dylan Groenewegen was disqualified and strongly condemned by governing body the Union Cycliste Internationale (UCI) for "dangerous behaviour", having appeared to nudge his Dutch compatriot into the barriers in a sprint finish.
Tests revealed Jakobsen did not suffer brain or spinal injuries, but he remains in a coma following an operation and doctors will attempt to wake the 23-year-old up later on Thursday.
Deceuninck-QuickStep said in a statement: "Fabio had facial surgery during the night. His situation is stable at the moment and later today the doctors will try to wake Fabio up."
Jumbo-Wisma, Groenewegen's team, issued an apology and said an internal review will take place.
"Our thoughts go out to Fabio Jakobsen and other people involved in today's terrible crash in the Tour of Poland. Crashes like these should not happen," the team tweeted.
"We offer our sincere apologies and we will discuss internally what has happened before we may make any further statement. #TDP20."
