Arsenal boss Mikel Arteta admits their physios need to check on Jurrien Timber after victory over Nottingham Forest.
Timber limped off on 50 minutes.
Arteta said, "The physio and docs looked at him and were happy to continue. Straight away in the second he made a movement and it felt funny.
"We will have to assess him."
He added, "Welcome to the PL. I think that's the headline. We were dominant. We deserved to win the game. We were 2-0 up and didn't take the chances. It was more about the feeling than actually what happened."
