Crewe boss Dario Gradi is weighing up a move into the loan market.
Gradi does not want a lack of depth in his squad to derail the club's League Two promotion challenge.
"I'd like to improve the cover we've got with a player or two," said Gradi, whose team climbed to seventh after beating Aldershot 3-1 on Saturday.
"We'll try to bring some in, but first we need to identify them and then see if there's the possibility we can get them."
