It's a major boost for the Reds as Gill has been their most influential forward in their opening three matches and they'll need him to be at his best against the bruising Sharks pack on Sunday morning.
Former Brumbies coach Jake White's new team have brushed aside the Bulls, Hurricanes and Lions with an abrasive power game.
With huge Springbok forwards Bismarck and Jannie du Plessis, Tendai Mtawarira, Willem Alberts and Ryan Kankowski, the Sharks will again aim to overpower Queensland, who are one of the smaller packs in the competition.
"We expect them to really come at us," Gill said. "But we're very excited about it."
Reds forwards coach Nick Stiles has worked hard on improving technical aspects at the set-piece and a pack mentality and their extra mobility will be keys to combating the Sharks' size.
