We've got an update on the Undertaker following his return to WWE at Sunday's SummerSlam pay-per-view.

Many readers who saw the Undertaker's return at SummerSlam noted that the Dead Man seemed to be out of shape and less muscular than the last time we saw him. He received medical clearance to get back in the gym just a few weeks ago, which explains that. Taker has been nursing a broken orbital bone, among other injuries. He was still experiencing vision problems as recently as last month but is expected to fully recover from the vision problems. He also suffered a concussion in the match where Rey Mysterio broke his orbital bone.

Undertaker will be feuding with Kane over the World Heavyweight title over the next few months, with current plans calling for matches at Night of Champions in September as well as Hell in a Cell in October. The first Undertaker vs. Kane match (of this chapter of their feud) has been booked for WWE's return to Madision Square Garden on September 25th.

Here's the updated card for the 9/25 MSG show:

* Kane vs. Undertaker for the World Title
* Bret Hart and The Hart Dynasty vs. Nexus
* Christian vs. Matt Hardy vs. Dolph Ziggler for the IC Title
* Big Show vs. Jack Swagger
