According to a live report on Prowrestling.net, Rey Mysterio appeared to be working in pain during the main event of Monday Night Raw this week against Alberto Del Rio. During a commercial break in the match, Del Rio stalled by taunting fans at ringside as Mysterio was spotted limping around trying to see if he could continue on his knee. He was also spotted having a conversation with a ringside producer. Mysterio was helped out shortly after the show went off the air.
