Former NC State Center Ted Larsen might have suffered a torn bicep. Larsen was signed as a free agent by Miami, and was expected to be the starting Left Guard for the Dolphins.
Larsen could miss the first few weeks of the season, or longer if it is revealed to be a full tear.
He might begin the season on injured reserve, with the Dolphins reserving the right to activate him if he’s available to play at some point this season. The NFL in May approved a rule allowing two players to be brought back from injured reserve (after week eight) per team this season, twice the number permitted last season.
