A bout featuring "The Ultimate Fighter 7" cast member Dan Cramer (3-1 MMA, 0-0 BFC) and Dennis Olsen (9-3 MMA, 0-1 BFC) is among some late preliminary-card additions to Thursday's Bellator 15 card.

A source close to the event today confirmed with MMAjunkie.com (www.mmajunkie.com) that bout, as well as Matt Lee (11-8-1 MMA, 0-0 BFC) vs. Ryan Quinn (2-1 MMA, 0-0 BFC) and Brylan Vanartsdalen (0-0 MMA, 0-0 BFC) vs. Richard de Los Reyes (1-0 MMA, 0-0 BFC).

Bellator 15 takes place April 22 at Mohegan Sun Arena in Uncasville, Conn.

As with all Bellator shows, Bellator 15 airs live on FOX Sports Net (check local listings to assure the event isn't preempted), and highlight packages air Saturday on NBC, Telemundo and mun2.

Cramer, who made the semifinals on "TUF 7," went 1-1 in the UFC and was released after a UFC 101 loss to Matthew Riddle. He's since moved up to middleweight for decision victories over Ron Jackson and Ever Nunez. His opponent, Olsen, is a Northeast-based fighter who enters Thursday's show with a 6-1 record in his past seven fights. (The lone loss came to Dave Branch at Bellator 11 in 2009.) Most recently, Olsen stopped another "TUF 7" cast member, Mike Dolce, via third-round stoppage.

Meanwhile, Lee, a Massachusetts-based fighter who's competed with major organiztions such as Strikeforce, BodogFIGHT and Rumble on the Rock, has won two of his past three fights following a tough stretch in which he lost to notables Eddie Alvarez, Jorge Masvidal and Dale Hartt. He now meets Quinn, who looks to rebound from his first career loss.

Finally, Vanartsdalen, a National Guard/Army recruiter, makes his pro debut after an impressive 6-0 amateur record. He meets de Los Reyes, who made a pro debut at a September WFL event with a first-round submission victory over Josh Henderson.
