Tranmere have confirmed the re-signing of midfielder Steve Jennings on non-contract terms.
The 28-year-old has returned to Prenton Park after leaving in 2009 for Motherwell on a free transfer.
His previous spell with Rovers saw him make 167 appearances and score 10 goals following his promotion to the first team from the youth ranks.
Jennings has been without a club since having his contract cancelled by Coventry in September following 49 appearances for the club.
He has been registered in time to face Rotherham on Tuesday night.
