As noted, Wrestling Inc. reader @_dustin96 passed along the photo below of The Undertaker with Kevin Dunn outside of the arena before last night's RAW. Taker was said to be limping pretty badly. He underwent hip surgery earlier this fall, and was photographed using crutches in October. He appeared at a Cleveland Cavaliers vs. New York Knicks NBA game in late October and just recently appeared on the 900th episode of SmackDown and was able to move around without noticeably limping.
Taker's wife, Michelle McCool, and his children were at last night's RAW as well and sat ringside for the whole show on the side of the hard camera.
