Northampton striker Adebayo Akinfenwa faces a spell out after he suffered a fractured jaw against Crawley at the weekend.
The injury is not as bad as initially feared, but Akinfenwa faces around two weeks out.
"Obviously it's disappointing but hopefully he will only be out for a couple of weeks," said Town boss Gary Johnson.
"Originally we thought he was going to be out for around six weeks so the news is a bit better than we first feared.
"It's not ideal but we just have to deal with it and it gives someone else the chance to come in.
"We have been looking at several options and we will do what we feel is best for the club and the team, starting at Port Vale on Friday night."
