The Boston Breakers announced today that defender Bianca D’Agostino will miss the 2013 due to a partially torn ACL.

“Losing Bianca is a big loss for us, especially with the other injuries we’ve had, losing Casey Short, who I thought was someone who could play left outside back for us, and the retirement of Heather Mitts,” Boston Breakers Head Coach Lisa Cole said. “Bianca was a good option, and we felt pretty good about the solution to that issue, and now we lose her as well. She’s a good soccer player, a good, young player, and I’m sure she’ll come back even better than ever. But for us, it’s something that’s going to hurt us down the stretch.”

D’Agostino was a mainstay for the Breakers back-line in 2012, starting 12 out of 13 matches and playing a total of 1,082 minutes.

According to the Breakers, D’Agostino will undergo surgery on her right knee and begin physical rehabilitation very soon.

D’Agostino is the second Breakers player this year to be sidelined with an ACL tear. Casey Short, the first pick in the NWSL Draft, suffered an ACL tear during a U.S. U-23 Women’s National Team match in February and will also miss the 2013 season.
