A matchup of undefeated welterweights has been booked for UFC 194 in December as Ultimate Fighter Brazil winner Warlley Alves will meet Colby Covington.

The fight booking was announced by the UFC on Wednesday.

UFC 194 will come from the MGM Grand Garden Arena on December 12 and will be headlined by a featherweight title unification bout as champion Jose Aldo meets interim champion Conor McGregor.

Alves (10-0) won the middleweight tournament during The Ultimate Fighter Brazil 3 and immediately dropped back down to the welterweight division. He is coming off a submission win earlier this month against Nordine Taleb and two of his three wins in the UFC have come by submission. Covington (8-0) made his UFC debut last year and has gone 3-0 in the promotion. His most recent win came in May as he defeated Mike Pyle by unanimous decision.
