Martin Brittain has been handed a further opportunity to prove his worth to Carlisle, after the League One side handed him a one-month deal.
The 22-year-old has been training with Neil McDonald's side in pre-season, and the former Newcastle man has earned himself a chance to impress as Carlisle kick off their new campaign.
Brittain played a key part in his new side's 2-1 win over Blackpool in a pre-season friendly, and McDonald has been pleased with his trialist'
McDonald told the club's official website: "He's enjoyed himself and done well since he got here, and he showed us last weekend that he can fit in with the way we like to play.
"We now need a little bit more time to have a look at him, so we're pleased to have him here for this month-long period.
"We can see what happens from there."
