Muhammed Lawal has lost an opponent for next month’s Bellator 123 event, but a replacement bout is in the works.

“King Mo’s” original opponent, light heavyweight Tom DeBlass (9-2 MMA, 1-0 BMMA), has suffered a knee injury and was forced off the card. Lawal (12-4 MMA, 4-3 BMMA) is now expected to fight Bellator newcomer Marcus Sursa (13-8 MMA, 0-0 BMMA).

MMAjunkie today confirmed the change with Sursa’s rep at All Star MMA. Sherdog.com initially reported it. However, Bellator officials cautioned that bout agreements haven’t been signed and that the fight isn’t official.

Bellator 123 takes place Sept. 5 at Mohegan Sun Arena in Uncasville, Conn. The main card, which goes head-to-head with UFC Fight Night 50, airs on Spike TV following prelims on Spike.com.

Lawal vs. Sursa would be part of the main card.

Lawal, a former Strikeforce champion, fights for the first time since a narrow unanimous-decision loss to Quinton Jackson at Bellator 120, which hosted the duo’s Season 10 tournament final. The loss prompted a post-fight outburst from Lawal directed at since-ousted Bellator Chairman and CEO Bjorn Rebney.

Sursa, meanwhile, is a 31-year-old Texan who makes his Bellator debut following back-to-back submission victories over WEC/Bellator vet Eric Schambari (15-6) and Andrew Kapel (7-4) in his two most recent bouts. In 13 career wins, he owns 12 stoppages.
