WWE Summerslam 2013 live stream free: Start time, how to watch online John Cena, CM Punk and more

WWE SummerSlam 2013 takes place tonight at 7 p.m. ET with a huge lineup of top action from the WWE's biggest names.

The SummerSlam 2013 fight card will start with WWE Champion John Cena vs Daniel Bryan, and that should prove a great spectacle for WWE fans this weekend.

The event kicks off from the Staples Center in Los Angeles, California and can be watched online through live stream with the details provided below.

The undercard tonight is exceptional with some fantastic matches lined up, however, it will no doubt be the main events that get the most people interested, and there should be a large pay-per-view audience joining tonight.

Daniel Bryan will be challenging for John Cena's WWE Championship belt, and Brock Lesnar will be fighting CM Punk. Those two matches should provide a spectacular base for a great show tonight.

Triple H will feature in the title match as the special guest referee, with Vince McMahon making it clear he doesn't want either man to win.
