Mesut Ozil has suffered an injury blow in Arsenal's Champions League draw at Bayern Munich.
The 1-1 result saw Arsenal bundled out of Europe 3-1 on aggregate.
Ozil was substituted at half-time with a hamstring problem.
On the loss of Ozil, boss Arsene Wenger said: "It looks quite serious.
"I don't know (how long he will be out for), but for sure he is out (of the Tottenham game on Sunday).
"We have to make a scan tomorrow to see how bad it is but he's out for at least a few weeks. I hope it's not too bad."
