A change was made to the lineup for UFC on FX 4 after Matt Riddle withdrew from the card for undisclosed reasons. Replacing him in a match-up with Luis Ramos will be fellow Ultimate Fighter alumnus Matt Brown who announced the bout himself via Twitter.

No official confirmation has come from the UFC yet.

Brown will be looking for his third straight win when he faces Ramos at the June 22 event. “The Immortal” was last seen outpointing Stephen Thompson in a terrific tussle last month at UFC 145. The performance improved his overall record to 14-11 and was his seventh inside the Octagon.

The 19-7 Ramos could be fighting for his job at the show after suffering a 40-second knockout to Erick Silva in his promotional debut this past August. Prior to the stumble the Brazilian had won a trio of consecutive clashes.

UFC on FX 4 features a five-round main event between lightweights Clay Guida-Gray Maynard with other announced fights including Rick Story-Brock Jardine, Sam Stout-Spencer Fisher, and Ross Pearson-Cub Swanson.
