Countdown To UFC 137 To Air On Spike TV Tonight

While the card lost it's biggest attraction, the show must go on. Tonight on Spike TV at 11:30 p.m. ET 'Countdown to UFC 137' will ostensibly focus on the main event welterweight bout between B.J. Penn and Nick Diaz.

Previous 'Countdown' editions have been an hour long and covered the main, co-main and featured bout of the fight card. However, with multiple changes to the main event and fight cancellations, the UFC likely does not have sufficient footage to air content for a 60-minute time slot.

In case you miss it, Spike TV will air a replay at 3:30 p.m. ET on Wednesday and 1:30 p.m. ET on Saturday. Versus will air a replay on Thursday at 8 p.m. ET.
