The following is from WWE.com:
STAMFORD, Conn. – World Wrestling Entertainment has made arrangements, given innumerable logistical challenges and obstacles, to move its internationally televised broadcast, WWE Monday Night Raw to Los Angeles' STAPLES Center. The live televised event, which was scheduled to take place at the Pepsi Center in Denver this Monday, May 25th, will take place live at the STAPLES Center at 5:30 p.m. PT.
Tickets for Monday Night Raw in Los Angeles will become available tonight at 8 p.m. ET.
WWE was forced to seek alternative arrangements due to the Pepsi Center’s double-booking of May 25 for both WWE Monday Night Raw and Game 4 of the NBA Western Conference Finals. The event will now take place live from the home of the Denver Nuggets' opponents, the Los Angeles Lakers.
Denver fans wishing to receive a refund for their tickets to the originally scheduled Pepsi Center event must return tickets to the original point of purchase.
