Pic: Anthony Pettis brings in heavyweight training partner one week out from UFC 185

Ultimate Fighting Championship (UFC) lightweight kingpin Anthony Pettis is set to defend his belt for the second time as he is scheduled to take on No. 1 ranked contender Rafael Dos Anjos next Saturday night (March 14, 2015) live on pay-per-view (PPV) from inside the American Airlines Center in Dallas, Texas.

Watch the extended preview for the PPV event here.

With only about a week to go before "Showtime" hits the Octagon for the sixth time, the UFC champ decided to bring in a heavyweight "sparring partner" you likely wouldn't suspect.

From his Instagram:

For those of you who are not NFL football fans, that behemoth of a man next to the UFC champ is none other than Houston Texans' defensive end JJ Watt.

Hopefully those two men are simply exchanging pleasantries, as mixed martial arts (MMA) fans don't want to hear of any last second injuries to "Showtime" over the next few days -- especially if the champ wants to become the next BJ Penn.
