Mike Glennon has a rookie-type day

CHARLOTTE, N.C. -- There were moments in the past few weeks when it looked like the Tampa Bay Buccaneers might have something special in rookie quarterback Mike Glennon.

He was playing efficiently and with poise, especially during a three-game winning streak. Then, along came Sunday and a matchup with the Carolina Panthers. For one of the few times since he took over as the starter in Week 4, Glennon looked like he belonged back up the road in Raleigh, where he went to college at NC State. In a 27-6 loss to the Carolina Panthers, Glennon looked vulnerable.

"I don't know 'step back' as much as he maybe looked a little more like a rookie than he's looked," coach Greg Schiano said.

For the first time in his career, Glennon went through an entire game without a touchdown pass. And Glennon had two costly turnovers.

The first came with Tampa Bay trailing 7-6 with 12:38 left in the second quarter. After Glennon hit Vincent Jackson with a 60-yard pass, the Bucs had a first-and-goal at the 4-yard line. But, on third down, a scrambling Glennon lost his grip on the ball. Carolina defensive tackle Dwan Edwards pounced on the fumble and that started the onslaught.

"The first one wasn't really a careless mistake," Glennon said. "Just the ball slipped out of my hand and it really hurt us because we would have gotten at least three points in that situation."

Glennon also looked bad on a third-quarter interception. His pass, intended for Jackson was woefully underthrown.

"I tried to make a play and I should have just thrown it away," Glennon said.

Glennon finished with 14 completions on 21 attempts for 180 yards. He was sacked five times and had a 73.5 passer rating.

"I think it is always a learning moment," Glennon said. "Like I always say, you can learn from the good; you learn from the bad. And there was some bad today that I will learn from. We will go back and watch the film and we will make the corrections."
