Speaking in his post-match interview on Saturday, the Gaffer confirmed that Keohane, who was forced off with a foot injury during Tuesday night’s against Stevenage, has broken his foot.
He could now be out for up to three months.
“Jimmy Keohane is going to be quite long term,” said Stockdale.
“[It will be] 10-12 weeks with a broken foot, so that’s disappointing.
“He’ll see a specialist over the next day or two to see if it needs pinning or some kind of surgery.”
Alex Newby missed Saturday’s match against Exeter City, and Stockdale says he sustained an injury during training on Friday.
“Alex pulled up in training yesterday with a bit of a groin injury, so he wasn’t available.”
