LONDON (AP) — Chelsea midfielder Oscar is out of the hospital following a heavy collision with an opponent during a Premier League game that left the Brazil international with a swollen face.

Oscar was injured about 15 minutes into the 0-0 draw at Arsenal on Sunday when goalkeeper David Ospina collided with him. The midfielder continued playing after treatment, but was substituted at halftime and taken to the hospital to have some scans.

Chelsea manager Jose Mourinho said Monday that Oscar "went immediately to his house yesterday night" from the hospital and slept at home. Oscar is expected at the club's training ground on Monday.

Asked if Oscar had sustained a concussion during the collision, Mourinho said: "I'm not sure of that. We saw his face was swelling at halftime, we don't want to go for any risks. We made that decision."

Mourinho said Oscar will be traveling with the rest of the Chelsea squad for Wednesday's match at Leicester, but didn't confirm whether he was available to play.
