Channing Tatum's Gambit has made it out of the Void and into the sprawling cast of Avengers: Doomsday. And though he does indeed play a major part in the film, Tatum himself has had to sit out of filming some important scenes because of a leg injury sustained on set (via Variety).
The exact circumstances of how Tatum was injured are unclear, but fans can rest assured that it won't stop Gambit from appearing in the movie, including in a "big fight" with Robert Downey, Jr.'s Doctor Doom. But it won't be Tatum himself in some fight scenes, with his double instead taking on the fight scenes while Tatum appears in close-ups and dialogue scenes.
