WWE is reportedly keen to work with UFC middleweight Chael Sonnen. Sonnen, who lost to Anderson Silva at UFC 148, is being targeted by WWE to be involved with the promotion in some way. It's unknown whether this means wrestling, an extended appearance or just a one-off.
Sonnen is friends with CM Punk, who nearly escorted Sonnen to the ring for a previous bout before WWE said no to it. Sonnen also has been working with Steve Austin on strength and conditioning training.
