Arsenal boss Unai Emery has played down fears over an injury to Alexandre Lacazette.
The Frenchman scored on the stroke of half-time to pull the scores back to 2-1 in the North London derby on Sunday.
Pierre-Emerick Aubameyang made it 2-2 after Lacazette was replaced with 25 minutes remaining in the match.
Asked about the injury after the game, Emery said: "Yes, I think it's [a hamstring problem].
"It's not severe."
