Chatfield, Oregon's all-time leader in wins and shutouts, tore the ACL in her right knee during a training session. Typical rehabilitation period for an ACL injury is seven to nine months.
"It was a hard decision to make and it took a while to come to it," said Chatfield, "but it's the right decision for me. I'm going to graduate in June and I'm not going to lie, the injuries have been tough. It's very sad to close this chapter of my life a little earlier than I planned, but I'm also excited to start another one. I've been looking forward to graduation and doing a lot of things that I've put on hold for a long time to concentrate on soccer."
Chatfield suffered a broken right hand in a game against New Hampshire in 2006 and missed five games. Despite the injury, she set the school record with a 0.82 goals-against average in helping lead Oregon to its best finish in the Pac-10, a second-place showing with a 6-1-2 mark, and a 12-6-2 record overall.
She also sustained a broken left arm in a 2007 spring scrimmage against Portland and missed most of the spring season. Additionally, Chatfield suffered concussions during both her sophomore and junior years.
The Ducks will have a pair of young players contending for the starting goalkeeper spot in sophomore Tori Johnson and freshman Cody Miles when camp starts Thursday.
