Thornton (undisclosed) exited Friday's practice early, Sam Warren of The Athletic reports.
Thornton, who is coming off a 2025 season in which he caught 10 passes for 135 yards on 30 targets over 15 games, is competing with Jack Bech and Malik Benson for slotting in a Las Vegas WR corps that's led by Tre Tucker and Jalen Nailor. Any missed time won't help his cause, but in any case the team's No. 3 option at the position may not see heavy volume in 2026, with two-TE sets featuring Brock Bowers and Michael Mayer likely to be used frequently this season.
