According to PWInsider.com, Brock Lesnar is backstage at tonight’s RAW and is scheduled for an in-ring appearance.  The main event for RAW will be CM Punk vs Paul Heyman, on the final RAW before SummerSlam this Sunday.

The Big Show is also backstage at RAW, and is finally expected to make his return tonight.  As we reported earlier, The Big Show did return to action last night at a WWE Live event in Oakland, CA. Show replaced John Cena, who couldn’t make it due to transportation issues.

The plan is to have Big Show, Mark Henry and The Shield featured in a segment tonight, and possibly lead to a 3-on-2 handicap match at SummerSlam.
