Loan signing Jayden Stockley is out of Torquay United's key home game against Southend United on Saturday.
The striker, who made his debut as a second-half substitute in the Gulls' last match at Scunthorpe United almost two weeks ago, has returned to his club, Bournemouth, for treatment to a calf strain.
The 20-year-old forward picked up the injury in training with United, and manager Alan Knill said: "At first, we feared that Jayden might be out for a month or more, but hopefully he will now be back next week.
"In the circumstances, it was more beneficial for him to go back to Bournemouth and use their facilities for his treatment."
Stockley's absence, so soon after joining the club, is just the latest in a cruel run of injuries which has dogged United's season so far.
Still on the sidelines is senior midfielder Ben Harding, who has now been out for ten weeks with a foot injury.
The unavailability of the former Aldershot Town and Northampton Town player has been a growing frustration for everybody concerned, but United physiotherapist Damian Davey was quick to put the case into perspective.
"I know people have been frustrated, but these injuries are often hard to clear up," said Davey. "Ben has the same injury as Andy Carroll at West Ham, and look how long he's been out."
Harding has been doing some light work and, following more treatment, hopes to step it up next week.
Knill, meanwhile, is trying to secure French midfielder Damien Mozika to a permanent deal.
At the moment Mozika, who also played under Knill at Bury and Scunthorpe, is playing on a non-contract agreement. That was put in place recently after Mozika, 26, returned to action after nine months out with a hamstring injury.
He has started United's last four matches, and Knill revealed: "We are in negotiations with Damien's agent, but nothing is signed and sealed yet.
"When players come back from injury, especially the sort that Damien has had, they often go hell for leather and then they can hit a bit of a wall.
"I thought Damien looked a bit tired at Scunthorpe and, although we know he's fit, it's all about match-fitness.
"The last two weeks, when we haven't had a game, should have done him some good, because he's been able to do plenty more work."
