Manchester United winger Tom Cleverley has collected a knee injury on-loan at Wigan Athletic.
He is not expected to return to action until the meeting with Newcastle United in mid-October.
"Tom will probably be out for at least the next two weeks," Latics boss Roberto Martinez told the Evening Post.
"He has a little problem with the medial ligament in his knee. But he is a very strong, fit boy and we hope he'll be able to heal quicker than is expected.
"In training, as you can imagine, it's very competitive with all the talent we have in the squad.
"Tom got a challenge and unfortunately he opened his knee a little bit. It's not great timing, because he had a real impact when he came on against Sunderland.
"He didn't need any settling in period at all and that's the sign of an excellent player. The good news is it's not going to be a long lay-off, but it's frustrating nonetheless."
