More matchmaking: Tito Ortiz retirement bout set, Demian Maia drops down, and more

With no events on the books until Apr. 14, the UFC has plenty of time to make matches for the spring and summer run of events.

-- Tito Ortiz will fight Forrest Griffin one more time. In what is expected to be Ortiz's final fight before retiring, the pair will meet up at UFC 148 in Las Vegas on July 7. The two are 1-1 against each other, with Ortiz taking their bout at UFC 59 and Griffin winning at UFC 106. Both were split decisions.

-- Also at UFC 148, former championship contender Demian Maia will debut at welterweight. He'll make the move down from middleweight and face Dong Hyun-Kim.

-- Featherweight prospects Jimmy Hettes and Steven Siler will square off at UFC on FX 4 in Atlantic City. Hettes will put his undefeated record on the line against Siler, who has two wins in the UFC.

-- In a fight that will surely be fun to watch, Josh Neer will fight Mike Pyle at UFC on FX 3 on June 8. Neer won four of his five fights by TKO, and Pyle is coming off a TKO of Ricardo Funch.
