Peterborough United midfielder Lee Frecklington may require surgery, but Lee Tomlin's knee injury is not as bad as first feared.
Both players were forced off during the 1-0 win over Coventry at London Road on Saturday - forward Tomlin with suspected ligament damage and midfielder Frecklington due to a groin problem.
Posh were initially concerned that Tomlin had suffered an injury similar to that which has ruled captain Grant McCann out of action for up to 10 weeks.
Tomlin is expected to be missing for just a few weeks, however, team-mate Frecklington is being lined up for an operation.
"Lee Tomlin's injury doesn't look as bad as we first thought, but he'll miss a few games," manager Darren Ferguson told the Evening Telegraph.
"Lee Frecklington has had a problem in his groin area for a while now so it might be that we have to bite the bullet and book him in for an operation."
Ferguson is confident his squad is strong enough to cope with the absences, but any more injuries could force him into the transfer market.
He added: "We still have plenty of talent to choose from, although if we pick up more (injuries) I might have to look at bringing in a player or two."
