Buccaneers quarterback Josh McCown is undergoing a second test on his injured thumb, Alex Marvez of FOX Sports reports Friday. McCown left Thursday's game in Atlanta in the second quarter after hitting his hand on a helmet during a throw. According to the report, he is expected to miss "several weeks" with the injury.
If that is the case, the Buccaneers will turn to Mike Glennon moving forward. Tampa Bay will have 10 days before their Week 4 matchup at Pittsburgh.
