DiNozzo (Michael Weatherly) is the most popular male on television according to his Q score (the metric used to determine appeal of celebrities, brands and TV shows), but he meets his match on NCIS this season when Gonzalez shows up.

"When you're in the kind of shape I'm in and you see Tony Gonzalez, you feel really out of shape," Weatherly said in between doing jumping jacks with ET's Brooke Anderson. "He's a brick house."

Weatherly was being a little modest, considering his recent 35-pound weight loss.

Gonzalez's appearance seems to be a part of an effort to integrate CBS football analysts into CBS scripted series. While he's a future Hall of Famer for the NFL, Gonzalez's acting chops have been less frequently tested.

"I played Christopher Columbus' brother when I was in fourth grade, so I think I'm ready for this role," said Gonzalez.

NCIS airs Tuesdays at 8/7c on CBS.
