The New England Free Jacks, a Major League Rugby expansion team, have signed an agreement to play their home games at the Union Point Sports Complex in Weymouth.

A stadium, seating and entertainment infrastructure will be built surrounding an all-weather field. One of the four lighted synthetic turf fields in the complex is a rugby-specific pitch.

Alex Magleby, co-founder and CEO of the Free Jacks, said he is excited about the team’s home. It has played three matches at Union Point.

“Numerous improvements have been made and are underway at Union Point since last spring, and we will make additional infrastructure investments ahead to continue to build toward a very unique, friendly and fun fan experience.”

Jerry Shafir, the co-owner of Union Point Sports Complex, said the decision by the Free Jacks is a victory for the region and the rugby community.

“Union Point’s rugby mission is to be a development center for high school, collegiate and club rugby, and the arrival of the professional game is truly remarkable for our venue,” Shafir said.

The team will play eight regular-season home games, starting in February. It will also use the sports complex for indoor training.

Further details of the plan were expected to be announced this week.

The Free Jacks will become the area’s second major professional sports team, joining the Boston Cannons of Major League Lacrosse, who play at Quincy Veterans Stadium.

Major League Rugby is expanding from nine to 12 teams in the U.S. and Canada for the 2020 season.
