League Two live updates
West Ham assistant boss Neil McDonald has turned down the chance to become Carlisle manager.
Sam Allardyce's number two was in the frame to replace the sacked Graham Kavanagh at the club where he previously had a spell in charge eight years ago.
But McDonald has decided to stay at Upton Park leaving the Cumbrians, currently bottom of League Two, looking elsewhere for a new boss.
Tranmere have appointed Rob Edwards as their new manager, the Sky Bet League Two club have announced.
The 41-year-old Edwards is the permanent successor to Ronnie Moore, who was suspended by Rovers in February after being charged by the FA for breaching betting rules and then sacked last month after pleading guilty.
