UFC featherweight title challenger Brian Ortega needs medical clearance to free him from a potential six-month suspension.

After a cageside doctor ruled Ortega (14-1 MMA, 6-1 UFC) unable to continue a fight with champ Max Holloway (20-3 MMA, 16-3 UFC) at UFC 231, he was given a possibly lengthy timeout.

The medical suspensions were issued by the Ontario Ministry of Tourism, Culture and Sport, which regulated the pay-per-view event this past Saturday at Scotiabank Arena in Toronto. MMAFighting.com first reported them.

Ortega’s heart didn’t go unnoticed by UFC President Dana White, who nonetheless praised the commission doctor for stopping the bout after a brutal fourth round.

In other notable suspensions, Canadian welterweight Chad Laprise (13-4 MMA, 6-4 UFC) suffered a knockout loss to Dhiego Lima (13-7 MMA, 2-5 UFC) and now needs medical clearance to avoid a six-month suspension.

Additionally, Brazilian welterweight Alex Oliveira (19-6-1 MMA, 9-4 UFC) is suspended for 60 days after his forehead was sliced open by an elbow from Gunnar Nelson (17-3-1 MMA, 8-3 UFC) on the pay-per-view main card.
