Promotion officials announced the pairings on Thursday. Bellator 155 takes place at CenturyLink Arena in Boise, Idaho, on May 20 and is headlined by a middleweight title clash between Rafael Carvalho and Melvin Manhoef. Held-Jansen and Gormley-Beltran will both appear on the main card, which airs on Spike TV beginning at 9 p.m. ET/8 p.m. CT.
Held saw a six-fight winning streak end at Bellator 145, as he dropped a five-round verdict to reigning 155-pound champ Will Brooks in November. Meanwhile, Jansen had a seven-bout streak snapped by Brooks in a five-round defeat at Bellator 136 in April.
Gormley, a two-time UFC veteran, lost to Dan Charles via second-round KO in his promotional debut at Bellator 143 this past September. Beltrran is 2-3 in Bellator but is coming off a first-round stoppage of Lamont Stafford in December on the regional circuit.
