Tagovailoa (back) was listed as a non-participant on Monday's estimated practice report, per Travis Wingfield of the Dolphins' official site.
The Dolphins didn't practice Monday, but as expected, Tagovailoa wouldn't have been able to participate after getting banged up during Sunday's win over the Bills. Head coach Mike McDaniel said earlier Monday that the quarterback is dealing with back and ankle soreness and was noncommittal about his status for Thursday's game against the Bengals. Tagovailoa briefly exited during the second quarter Sunday after he stumbled trying to make it back to the huddle following a third-down sack. McDaniel confirmed that the lefty isn't in the concussion protocol, per Hal Habib of The Palm Beach Post, but the league is going to investigate Miami's handling of the situation this week. If Tagovailoa ultimately can't go on a short week, Teddy Bridgewater would lead Miami's revamped offense Week 4.
