Joel Diaz Jr. headlines May 16 card

Undefeated junior lightweight prospect Joel Diaz Jr. will take on Tyler Asselstine in a scheduled 10-rounder that will headline a May 16 card at the Foxwoods Resort Casino in Mashantucket, Conn., promoter Lou DiBella announced on Monday.

The fight will headline an edition of Showtime’s “ShoBox: The New Generation” (10 p.m. ET/PT). In the co-feature, unbeaten junior middleweight prospects Frank Galarza (13-0-2, 9 KOs) and Sebastien Bouchard (9-0, 2 KOs) meet in an eight-rounder.

The 21-year-old Diaz (15-0, 12 KOs) recently signed a co-promotional deal with DiBella and light heavyweight contender Jean Pascal’s company. Asselstine (14-1, 7 KOs) was an amateur standout in his home country of Canada.

Galarza is coming off a spectacular second-round knockout of John Thompson on “ShoBox” on Jan. 17. Bouchard is a former two-time Canadian amateur champion and will be making his television debut.
