Right tackle Demar Dotson, the Bucs' most experienced offensive lineman, will undergo an MRI on his injured groin Saturday, three weeks before the season opener.
How would the Bucs replace Dotson if he had an extended absence? Second-year pro Caleb Benenoch, potentially the top backup at both tackle spots, filled in Thursday night when Dotson was hurt after only 11 plays. Coach Dirk Koetter said his run blocking looked better than his pass protection -- he was flagged for one of four holding penalties against the Bucs offense.
"He's doing a nice job in the run game," Koetter said.
