Longtime indie favorite Bryan Danielson signed a WWE contract late in the summer 2009 but had not appeared for the company yet.
On the January 4, 2010 Monday Night Raw, Danielson had his first WWE match, facing Chavo Guerrero before Raw went on the air live.
In a match that only the live fans saw, Danielson defeated Chavo and was reportedly able to win over the crowd.
