UFC 159 is beginning to fill up, though the event doesn’t take place until April.

Two bouts were made official by the promotion on Tuesday night, as light heavyweights Phil Davis and Vinny Magalhaes will square off, along with heavyweights Roy Nelson and Cheick Kongo.

Davis (10-1) defeated Wagner Prado to close out 2012, as his planned fight with Forrest Griffin was scratched after Griffin suffered a training injury.

Magalhaes (10-5), a former runner-up on The Ultimate Fighter, submitted Igor Pokrajac in his Octagon return.

The two fighters started a Twitter feud, which led to the match being made.

Nelson (18-7) earned his second straight win by finishing Matt Mitrione last month, while Kongo (18-7-2) is 3-1 in his last four.

Kongo was originally asked to face Nelson in December, but declined the bout.
