JONNY Walker has joined League One outfit Cougars on loan for the rest of the season.

The Bulls prop joined his hometown club last winter but has struggled to establish himself at Odsal this year.

He has spent time on loan at Dewsbury and will now join Keighley for the remainder of their campaign.

Walker previously spent time on dual-reg at Cougar Park during the 2013 season, when he was a Castleford player, and looks certain to feature in Sunday's home game against York.
