Exeter City's management team say they are impressed with the attitude of ex-Yeovil defender Curtis Ujah.
The 22-year-old, who began his career at Reading, has been training with City for the past few months as he recovers from injury.
Ujah played 30 minutes in Tuesday's pre-season friendly at Mangotsfield.
"He's certainly given everything he's got and you can't help but admire him for that," reserve team boss Andy Tilson told BBC Radio Devon.
"He's really worked his socks off to try and get himself fit," added Tilson.
And City manager Paul Tisdale has not ruled out the possibility of Ujah's time at the club turning into a contract.
"We're just helping him get back to fitness, but if that means we benefit from it in the end we'll have to wait and see," Tisdale told BBC Devon.
"At the moment there are no plans for him to move into our first team. He's spending some time with us, but at the moment it's no more than that."
