Nate Landwehr calls out Billy Quarantillo and Shane Burgos after UFC San Diego win

Nate Landwehr and David Onama started at a frantic pace, taking the fight to each other from the initial bell. 'The Train' was dropped in the opening frame itself but managed to recover and land some significant damage of his own.

Although Landwehr took the majority of the damage in round one, he was visibly the fresher fighter going into the second round. Onama displayed immense heart, managing to stay in the fight despite appearing to have emptied his gas tank. The Ugandan even dropped his opponent in a frantic exchange in the closing seconds of the bout. However, 'The Train' did enough to earn a majority decision victory in the end.

In his post-fight octagon interview, Landwehr issued call-outs to featherweight prospects Billy Quarantillo and Shane Burgos. The 34-year-old said:

"I'll tee-off on Billy Q, I'll downgrade Hurricane Shane down to a thunderstorm."
