Check this out: What in the world is Vince Wilfork wearing?

If football fans are looking for more incentive to tune into the latest episode of "Hard Knocks" on Tuesday, the Houston Texans offered a preview of what to expect on the show — Vince Wilfork rocking a pair of overalls. Erm, shortalls. Sans shirt.

Judging from the photo, head coach Bill O'Brien isn't quite sure what to make of Wilfork's fashion choice either, but it appears the 6-foot-2, 325-pound nose tackle is comfortably fitting into his new surroundings in Houston.

The fourth episode of "Hard Knocks" premieres Tuesday night on HBO.
