Brighton's new signing Matt O'Riley suffered a severe ankle injury just nine minutes into his debut against Crawley Town, necessitating surgery. O'Riley, who joined Brighton from Celtic for £25 million, was hurt by a heavy tackle from Crawley's Jay Williams. Brighton manager Fabian Hurzeler criticized the tackle as 'ridiculous' and expressed uncertainty about O'Riley's recovery timeline. Despite this setback, Brighton secured a 4-0 victory over Crawley, with goals from Simon Adingra, Jeremy Sarmiento, Adam Webster, and Mark O'Mahony. The injury may impact the club's decision on the potential transfer of Scotland midfielder Billy Gilmour to Napoli. O'Riley remains optimistic about his recovery, aiming to return stronger.
