University of Tennessee graduate Bill Duff — who you might recall was an outstanding lineman in 1990s for the Vols — is crossing over to the movies.

Since ending his professional football career (among his moves was one to the ill-fated XFL), the 6-foot-4, 290-pound dude, whom I refer to respectfully as "Mister Duff," recently finished playing former Philadelphia Eagle Stan Walters in the football movie "Invincible."

He also auditioned for a role in "Rocky VI," which is now in production. The fifth sequel in the "Rocky" line stars Sylvester Stallone in the title role once again and former "Gilmore Girls" guy Milo Ventimiglia as his son.
