Brock Lesnar takes on John Cena tonight in the main event at WWE Extreme Rules.
Crunchsports.com will have full, live coverage of Extreme Rules online from 01:00 BST (20:00 EST)
Former WWE champion Lesnar is making his first in-ring appearance in almost eight years after quitting the company following his match with Goldberg at WrestleMania 20.
The 34-year-old bounced back from a failed bid to enter the NFL by turning his hand to mixed martial arts during his WWE exile, and in his brief career he became UFC heavyweight champion, registering wins over the likes of Randy Couture, Frank Mir and Shane Carwin.
Lesnar left the UFC at the end of 2011 and then shocked the world by returning to WWE earlier this month, confronting John Cena and hitting him with the ‘F5’ in the final moments of a Monday Night RAW broadcast.
Lesnar left Cena with a bloodied mouth when the pair clashed once again, and the leader of the ‘Cenation’ will be keen to get revenge in this Sunday’s Extreme Rules match in Chicago.
However, bookmakers Paddy Power, who are taking bets on tonight's top bouts, are expecting a winning return for Lesnar, making him the 2/5 favourite, while Cena is 7/4 to bounce back from his WrestleMania 28 defeat at the hands of Dwayne ‘The Rock’ Johnson.
