Gilbert will be piggybacked by Emerson Hancock during the former's start against Toronto on Saturday, Ryan Divish of The Seattle Times reports.
Gilbert and Hancock were originally supposed to work together in a piggyback game last weekend, but a last-minute change allowed the two pitchers to both make their own traditional starts. Now back in a piggyback plan, Gilbert could be limited to roughly five innings Saturday before Hancock steps in to potentially close out the game.
