 In May , McMahon signed another Handicap match , with the Spirit Squad facing Michaels . The match never started , however ; instead the Spirit Squad attacked Michaels , and , as part of the storyline , shattered his knee with a steel chair . McMahon brought Triple H to the ring to attack Michaels with a sledgehammer ; however , after Triple H felt that the Squad had disrespected him , he attacked the group . This led to Triple H and Michaels reforming D @-@ Generation X ( DX ) and they began a feud with the Spirit Squad . DX played various sophomoric jokes on the Squad and the McMahons , as well as defeating the Spirit Squad in handicap tag team matches at Vengeance and a clean sweep in an elimination handicap match at Saturday Night 's Main Event .
