THE Broncos have suffered a blow this morning for tomorrow's NRL Elimination Final in Brisbane.

International back rower Alex Glenn is out of the match after failing to recover from a calf strain suffered late last week.

Glenn first felt the problem in the final training run before last week's win over the Sea Eagles, and was subsequently left out of the match.

He will now miss the knockout final against the Dragons at Suncorp Stadium.

Coach Wayne Bennett will make the call on his replacement after the team has its last training session at the Clive Berghofer Centre this morning.
