Welterweights Thiago Alves and Jordan Mein will give their bout a second chance, as officials have confirmed them for UFC 183.

Set for January 31 from Las Vegas, the event features the return of Anderson Silva. The former UFC middleweight champion meets Nick Diaz in the main event.

Alves (20-9) and Mein were set to meet at UFC Fight Night 49 earlier this year, but Alves was forced out with an injury. After missing two years, he defeated Seth Baczynski.

Mein (29-9) is 3-1 in his last four, including two straight wins. He remained on the Fight Night card and defeated Mike Pyle via TKO.

Below is the current lineup:

Middleweight: Anderson Silva vs. Nick Diaz
