Carlisle boss Greg Abbott is yet to make a decision on trialist Femi Orenuga.
The winger, 19, was released by Everton over the summer and has been training with Carlisle for around 10 days. He will remain with the club for the rest of this week as Abbott weighs up whether to offer terms.
"Femi is a really nice lad and he has come here determined to work hard and to improve his fitness," Abbott told the club's official website.
He added: "Our schedule is really tight at the moment as we bounce from one game to another and ideally we would like to see him in a match environment.
"At the moment we are happy to have him here and he's happy to be here. That will continue as we go through another very busy week."
