In updated advertising on the Allstate Arena’s official website, former WWE Champion and UFC Heavyweight Champion Brock Lesnar is listed as making an appearance, as we noted previously on the website. The advertising does not state as to whether Lesnar will be wrestling at the event, however given the return last week and a pending fued with John Cena, that may become a possibility as early as this Monday’s WWE RAW.

The advertising for the event reads, “Brock Lesnar has returned to WWE for the first time in 8 years and he will be live in Chicago! See the former 2-time WWE Champion. Brock Lesnar is back in Chicago for the first time in 8 years for the WWE Extreme Rules pay per view. It’s a nigh of no limits, no boundaries, anything goes when the superstars of RAW and SmackDown take over the Allstate Arena for WWE Extreme Rules.”

WWE Extreme Rules takes place on April 29th, 2012 at the Allstate Arena in Rosemont, Illinois.
