Assumption College announced plans to construct a $3.2 million multi-sport stadium, which opened in September 2005. The stadium was the key capital project of the second phase of the Centennial Campaign. The stadium was constructed on the previous site of Assumption’s football/lacrosse field. The new facility supports six athletic teams (football, men's and women's lacrosse, men's and women’s soccer, and field hockey) and an outdoor intramural sports program on an infilled, synthetic turf field. It includes lights, elevated grandstand seating for approximately 1,200 spectators, a press box and a president's box.
Assumption College finished in the top six of the Northeast-10 President's Cup standings in 2014-15, 2015-16 and 2016-17. In 2015-16 the department finished a program-best third after winning conference championships in football and swimming and earning a runner-up finish in field hockey. In the fall of 2017, the football program won its second NE10 Title in the last three years and reached the NCAA Quarterfinals, where the program fell to Indiana (Pa.). The women's cross country program, meanwhile, placed second in the NE10 Championship and earned a second straight bid to the NCAA Championships - where they finished 27th. Field hockey advanced to the NE10 Title game, falling to eventual national champion LIU Post.
