Haynes King had a stunning performance in the Hall of Fame game but is now expected to miss time with a hamstring injury.
King threw for two touchdowns and ran for the game winner in a thrilling 33-30 win over the Panthers as preseason play began.
With the loss of a camp arm, the Panthers have signed Kyle Trask to a contract. This comes days after he was brought in for a look by the team.
The addition of Trask places him on the depth chart behind starter Bryce Young and Kenny Pickett.
A former second round pick of the Buccaneers, in his career Trask has attempted just 11 places.
