Featherstone prop Spencer Darley has re-joined Keighley for a second loan spell this year.
The front-rower has joined the Cougars for the remainder of the season from Rovers.
Darley spent a month on loan at Keighley back in February but it was ended prematurely through injury.
He arrived at Featherstone ahead of the 2029 season after spending time in the Leeds academy.
Darley played in the Rhinos’ Under-19s Academy Grand Final defeat to Wigan last season.
