The Ultimate Fighter season 13 got underway on Wednesday night on Spike TV and figures released today show the show pulled in an average of 1.5 million viewers and a 1.0 household rating.

Given that the show featured the UFC’s biggest pay-per-view draw Brock Lesnar as a coach opposite current No.1 heavyweight contender Junior Dos Santos, the figures may be seen as a little disappointing.

By way of comparison TUF season 12: St.Pierre Vs Koscheck drew 1.6 million in it’s debut, while TUF 11: Liddell Vs Ortiz did 1.9 million.

The UFC are believed to have paid Lesnar handsomely to convince him to appear on the show, and in return the former WWE star has been on the promotional trail heavily in the build up to the season premiere, appearing on the likes of ‘Late Night With Jimmy Fallon’, and on various ESPN shows.

So far it appears this hasn’t translated into a ratings boost, and with rumors spreading that there’s unlikely to be any headline-grabbing incidents between the two team coaches, it may be that the UFC and Spike have to settle for solid rather than sensational ratings this season.
