The Wyatt Family will be working a six-man match at this year's SummerSlam pay-per-view, most likely against Kane and two partners to be determined.
We noted before that WWE wanted to do The Shield vs. Kane and The Undertaker at SummerSlam but word now is that Taker re-injured himself in the last WWE TV spot he did with The Shield where they put him through the announcers table. Taker could be out of action until WrestleMania XXX.
Regarding Seth Rollins and Roman Reigns defending at SummerSlam, it could be against the team of Randy Orton and Sheamus or the team of Antonio Cesaro and Jack Swagger. We noted before that Dean Ambrose will likely defend theTitle against Christian at SummerSlam.
