The Denmark international had a debut to forget as he was forced off the pitch after just 10 minutes due to a harsh tackle, leaving him sidelined for the start of the season.
Brighton midfielder Matt O'Riley will now undergo surgery on his ankle after suffering a "bad" injury on his debut for the club against Crawley Town.AdvertisementAdvertisementO’Riley completed a £25m move to Brighton from Celtic on Monday which makes the injury even more frustrating for manager Fabian Huerzler who had the midfielder in his plans for the season.
"It is like we expected, it is a bad injury and he needs surgery on his ankle," said Hurzeler.
"I can’t say how long or when we expect him to be back because of rehabilitation. It is a tough one for us but we will try to support him the best we can."
The Brighton manager said the tackle was “ridiculous” and that O’Riley was "very disappointed" about his setback.
