John O'Sullivan has been ruled out for the remainder of the season with a hamstring injury sustained in the 4-3 victory over Oldham Athletic last week.
Physiotherapist Simon Farnworth revealed: "John has suffered some fairly bad damage to the hamstring, he's got a tear in a tendon as well as some of the muscle, which has been graded as a 3C tear.
"He has had some PRP (Platelet-rich Plasma) treatment in there and he'll obviously have to rehab now for roughly 8 to 10 weeks for this kind of injury."
The influential midfielder has made 46 appearances for the Shrimps this campaign, scoring five goals and providing eight assists.
"I'm devastated to be honest," added O'Sullivan.
"All season we've put in so much effort and to be ruled out for the final three or four games is hard to take.
"To get any injury at this stage is disappointing but hopefully the boys can finish the job.
"It's been a brilliant season but we want to finish it off now. For me personally it's the most I've enjoyed a season for a long time, so it's such a shame the injury is as bad as it is.
"At the time I didn't expect it to be this serious but it's a chance for someone else to come in and do well now.
"I'll be there on the sideline cheering the boys on and as I say hopefully we can finish the job and get promoted."
