In August 2002, Shawn Michaels would also return as a wrestler at SummerSlam after a hiatus of over four years. He would achieve great success, and won a World Championship in the first Elimination Chamber match at Survivor Series. The match between Shawn Michaels and Kurt Angle at WrestleMania 21 has been named one of the greatest matches in WWE history. Though Angle won the match, Michaels received praise for his "courageous effort". In 2006, Michaels would reunite with Triple H to once again form the popular 1990s group D-Generation X. They would have major feuds with The Spirit Squad, the McMahon family, and the newly established Rated-RKO (Edge and Randy Orton), which ended prematurely when Triple H suffered a torn quadriceps muscle in 2007.
