Officials today confirmed that Alexander Gustafsson vs. Vladimir Matyushenko and Chad Mendes vs. Rani Yahya will be featured on the UFC 133 "UFC Prelims" broadcast.
And for 134:
The two bouts set for the one-hour special include Spencer Fisher vs. Thiago Tavares and David Mitchell vs. Paulo Thiago.
Spike currently has four more preliminary events during the rest of 2011 after these two. With five pay-per-views tentatively scheduled over the fall and winter, it looks like one of the events won't have any fights featured on Spike. Ion has picked up those events to broadcast when Spike has passed, but it's unclear if that will continue in the future.
