Hart's absence in Sunday's Week 3 game against the Dolphins doesn't change much for the Bills. Hart is the backup to LG Roger Saffold, who was not mentioned on the team's injury report Wednesday. He has appeared on 19 offensive snaps through two weeks.

After the game between the Titans and Bills ended, Hart approached an unnamed Titans coach, confronted him and punched him in the face by the end zone near the tunnel. It's unclear what led to this, but it seems emotions were riding high after the Bills dismantled to Titans 41-7. Hart will be eligible to return September 26.

After starting 13 games for the Bengals in 2020, Hart signed with the Bills last offseason. He didn't make their final roster and bounced around practice squads and active rosters throughout the season. This included appearing in three games for the Titans, one of which was a start at left tackle. He ended the year by making a brief appearance for the Bills in Week 16. Strictly a backup, Hart will be fighting for a roster spot in training camp. 

Buffalo signed Hart four days after the Titans released the veteran. Tennessee signed Hart in October as a temporarily fill-in for Taylor Lewan, who went down to injury in Week 6. Bills OL Spencer Brown this week was placed on the reserve/COVID-19 list. Pro Football Focus grades Buffalo's offensive line as the 13th worst pass blocking unit this year.
