UFC on Fox might not always have the same star power as some of the promotion's bigger main events, but it has brought some very memorable fights in the past.
From Rafael Dos Anjos' first-round knockout of Cowboy Cerrone to Sage Northcutt's
surprise first career defeat against Bryan Barbarena, there's plenty to be said for the events.
And the upcoming UFC on Fox 20 already has some intriguing bouts lined up, with the main event yet to be confirmed.
Among those taking part is Alex 'Cowboy' Oliveira, who has not fought since losing to the
other Cowboy by submission at UFC Pittsburgh.

Oliveira will take on 9-3 fighter James Moontasri at welterweight, one of three fights at 170lb currently on the bill.
The other two involve Russia's Alexander Yakovlev against Ryan LaFlare and the last man beaten by Yakovlev - George Sullivan - up against Hector Urbina.
Only one other fight has been confirmed at the time of writing, with Dmitry Smolyakov, another Russian, making his UFC bow against Brazil's Luis Henrique Barbosa de Oliveira.
UFC on Fox 20 will take place in Chicago on July 23.
