Bibb, 23, made 17 appearances for the Wildcats last season, but will move south for a month spell with Harlequins, who were a prop short following the departure of Matt James earlier this week. He goes straight in to the squad for Friday’s trip to Leeds.
Wakefield head coach John Kear said: “It’s going to be great experience for Kyle and will enable him to stake a claim for a regular first-team place.
“Kyle’s not had much opportunity with so far this season because the team is travelling so well so at the moment so besides helping Harlequins through their injury crisis the loan period will be beneficial to both Kyle and the Wildcats.”
Meanwhile, hooker Kaye has joined Championship side Featherstone on loan.
