Update for June 6 Reality Fighting event

Reality Fighting, the MMA arm of the Marlborough-based organization NAGA (North American Grappling Association), has made a change to the card for its June 6 event at the Mohegan Sun resort in Uncasville.

The company originally scheduled a lightweight title fight between Jeremy Ross (6-5) and Andrew Calandrelli (6-4) as the main event for that evening. Reality Fighting spokespersons announced that Calandrelli had to pull out due to an injury and will be replaced by Tommy Marcellino, who started fighting with the organization about 14 years ago and has a 6-2 record with it.
