Roberto Martinez says the Killybegs man, who was a sub against Leicester last weekend, is available to start this time around.
“Seamus was fully fit from a medical point of view on Saturday and that was a real boost,” said Martinez ahead of Saturday’s clash with Arsenal.
“He has been working really well, and he was desperate to be part of the squad on Saturday.
“I think now it’s fair to say that he’s considered fully fit and ready to join the group and help the team in any game.”
The fitness boost is good news form Martin O’Neill ahead of Ireland’s Euro 2016 qualifier against Georgia.
