Rush will start Sunday's game at Pittsburgh after Tua Tagovailoa (oblique) was ruled out for Week 1 action, NFL reporter Jordan Schultz reports.
Tagovailoa suffered an oblique strain during Thursday's practice and now will join Michael Penix (knee) on the sideline this weekend. Rush handled the first-team reps in the final two sessions of Week 1 prep and thus will be under center Sunday, with Jack Strand backing him up. Because coach Kevin Stefanski told Marc Raimondi of ESPN.com on Friday that Tagovailoa is "week-to-week," Rush could be in consideration for multiple starts to kick off the 2026 campaign.
