Juan Adams vs. Chris de la Rocha, Adam Milstead vs. Mike Rodriguez announced for UFC on FOX 31

A pair of bouts in the UFC’s heaviest weight classes have been added to its upcoming return to Milwaukee.

The promotion announced Tuesday that a heavyweight bout between Juan Adams (4-0) and Chris de la Rocha (5-2), and a light heavyweight bout between Adam Milstead (8-2, 1 NC) and Mike Rodriguez (9-3) have been added to the UFC on FOX 31 card, which takes place at the Fiserv Forum in Milwaukee on Dec. 15.

Adams, 26, went 3-0 with the Legacy Fighting Alliance before earning a contract on Dana White’s Tuesday Night Contender Series this past July with a win over Shawn Teed. All of Adam’s wins have come via first-round knockout.

De la Rocha is coming off of a second-round TKO of Rashad Coulter at UFC 225 in June. The 39-year-old lost his first two fights in the promotion and was sidelined with a hip injury for two years before picking up the win against Coulter.

Milstead will look to rebound from the first official loss of his career. He dropped a split decision toJordan Johnson at UFC 222, and prior to that he was TKO’d by Curtis Blaydes, though the latter result was overturned to a no-contest when Blaydes later failed a drug test for marijuana. A 31-year-old fighting out of Pennsylvania, Milstead’s lone UFC win so far came against de la Rocha in a heavyweight bout back in May 2016.

Like Adams, Rodriguez is also a DWTNCS contract winner. The 29-year-old earned his spot with a first-round knockout of Jamelle Jones in August of last year, then dropped a unanimous decision in his UFC debut to Devin Clark at UFC 223.
