Wests Tigers have been granted a player exemption from the National Rugby League for Saturday's Round 21 clash against the Canterbury-Bankstown Bulldogs at ANZ Stadium.

Having originally been named in the run-on side at prop, Josh Aloiai has been ruled out with injury and will be replaced in the 21-man squad by Chris McQueen.

McQueen will come in to the squad in jersey 24 with Thomas Mikaele to start.
