The netting fell at about 9:40 p.m. Thursday after the Bruins' 3-0 win over the Washington Capitals.
A private ambulance service took the women to the hospital as a precaution, but their injuries are not considered life threatening.
No names were released, but police say both women were in their 20s.
What caused the netting to fall is unclear. It is intended to protect fans from pucks that fly over the glass.
