Next month’s UFC return to New Jersey has had a change on the prelims, and Tim Means will make a quick turnaround to get back to work.

Means (23-6-1 MMA, 5-3 UFC) will step in for injured welterweight Kenny Robertson (15-3 MMA, 5-3 UFC) to meet George Sullivan (16-3 MMA, 2-0 UFC) at UFC on FOX 15. UFC officials announced the change today.

Featuring a middleweight matchup between top contenders Lyoto Machida and Luke Rockhold, UFC on FOX 15 takes place April 18 at Prudential Center in Newark, N.J. The evening’s main card airs on FOX following prelims on FOX Sports 1 and UFC Fight Pass. The Means-Sullivan bout is slated for the Fight Pass prelims.

Means is coming off a “Performance of the Night” bonus-winning first-round TKO of Dhiego Lima at UFC 184 in Los Angeles a little more than three weeks ago. The victory was his third straight after a decision loss to Neil Magny, which came after a two-win run for Legacy FC outside the UFC.

Sullivan gets a home fight against Means. The New Jersey-based fighter, who trains with former UFC fighter Kurt Pellegrino, has won eight straight fights, including his first two bouts in the UFC. He debuted with the promotion at UFC on FOX 10, taking a unanimous decision from Mike Rhodes. He returned this past September and locked out Igor Araujo in hostile territory in Brazil, giving him knockouts in 11 of his 16 career wins.

Robertson kept his hot streak going in Sweden in January with a “Performance of the Night” bonus-winning knockout of Sultan Aliev midway through the first round at UFC on FOX 14. It was his third straight win and fourth in five fights. It also was his second bonus in the UFC. Now he puts his solid run on hold.

With the change in the lineup, UFC on FOX 15 now includes:

MAIN CARD (FOX, 8 p.m. ET)

Lyoto Machida vs. Luke Rockhold Yoel Romero vs. Ronaldo Souza Max Holloway vs. Cub Swanson Felice Herrig vs. Paige VanZant
