Celtic Star player just announced his departure.
Denmark’s O’Riley, who joined Brighton from Celtic in a deal reported by British media to be worth 25 million pounds, injured his left ankle following a heavy tackle by Jay Williams during the 4-0 win over League One side Crawley Town in the second round of the League Cup.
“He needs a surgery on his ankle. I can’t say how long he will be out,” Hurzeler told reporters on Thursday.
Crawley manager Scott Lindsey had apologised for the tackle that injured O’Riley after the match.
“Maybe we were a bit aggressive, maybe the referee missed it (the challenge) and I would like to apologise… I wouldn’t want anyone to be hurt,” Lindsey told reporters.
