Josh McCown expected to test thumb on Monday

Mike Glennon led a game-winning drive in Pittsburgh on Sunday afternoon to give the Buccaneers their first win of the season behind their best quarterback play of the young season.

Glennon got the nod because Josh McCown injured his thumb during Tampa’s humiliating Week Three loss to the Falcons and, based on Sunday’s play, the switch could become permanent if McCown is out for an extended period of time. McCown will try to find out how things look on that front on Monday.

Adam Schefter of ESPN reports that McCown will throw the ball to see how well he can sling it and if the pain from his torn ligament is tolerable. If it isn’t, McCown will head for surgery that would keep him out of the lineup for six weeks.

There’s been no public discussion of the quarterback plans moving forward in Tampa, but Lovie Smith may have given a hint while discussing how one win can change things after a rough start to the season.

“I definitely believe in momentum,” Smith said, via ESPN.com. “Sometimes nothing good happens until you just keep going. Once you get that momentum, you find a way to win. You have to experience it first. We didn’t know how to win.”

Belief in momentum would suggest sticking with Glennon after a 302-yard performance that ended with a celebration regardless of what McCown’s status is come Monday evening.
