Don't miss WWE Hall of Famer "Stone Cold" Steve Austin and former WWE Diva Stacy Keibler on NBC's Chuck this Monday night, Oct. 4, at 8/7 CT.

The popular series, now in its fourth season, stars Zachary Levi as Chuck Bartowski, a computer whiz who stumbles upon an encoded CIA e-mail that transmits sensitive spy secrets into his brain. This information has helped Chuck grow into a successful spy in his own right, embarking on high-stakes missions that pit him against some of the most dangerous people on the planet.

In this episode, The Rattlesnake reprises the role of cold-blooded mercenary Hugo Panzer, a close-quarters combat expert who is likely seeking some retribution after being thwarted by Chuck last season. Keibler, meanwhile, plays Greta, an undercover CIA operative who is portrayed by a different actor each week. (WATCH PREVIEW)
