I remember the show but I dont think that was it. He was an undercover cop i think and he was trying to bust an illegal fighting ring, every single person he fought had some theme. Like the football player, than I think he fought some kung fu guy and a wrestler. Reminded me of a Bolo Yeung movie, sorry but thats all i can remember.

1st and Ten.
