GREEN BAY, Wis. -- Green Bay Packers wide receiver Greg Jennings is used to earning a little camera time by catching touchdowns at Lambeau Field, but on Wednesday night, the NFL wide receiver will be appearing on the hit CBS drama "Criminal Minds."

Jennings has a cameo appearance as a lab technician during Wednesday night's episode (May 5, 8 p.m. CT). He has a few speaking lines in a short conversation with cast member Shemar Moore in his one scene.

"When you think about a lab technician, you think about the long white coat and glasses and everything, and that's what I was thinking," Jennings said via www.packers.com. "But it's more along the lines of me in the (forensics team) jumpsuit, taking the (dead) bodies out."

Jennings taped the episode in late March. He said the shooting for his scene took only a couple of hours, and he wasn't expecting the celebrity treatment he received.

He said he was given his own trailer. The crew members were all wearing Green Bay apparel during the filming of his scene, and he said Moore was particularly helpful with some on-the-spot acting lessons between takes.

"It was fun, it was fun," Jennings said via www.packers.com. "I was going in letting them know this is not what I do. I'm on the football field. That's me, that's my domain, but the cast members were great, giving me feedback. They opened their arms and helped me as much as possible and tried to make me look as good as possible."

Jennings got the invite after meeting a CBS producer a few years ago. The appearance didn't fit into his schedule until this spring.

"It was pretty detailed, and it's pretty neat what they do," Jennings said via www.packers.com. "Being behind the scenes and seeing how they set things up, it's neat how they put it all together."
