Tragedy has struck the New England Patriots as former defensive end Ron Brace has died at the age of 29.

Brace played for Boston College before being drafted into the NFL in 2009 and played for the team 39 times over four seasons before being released.

Brace died at his home in Springfield, Mass. on Saturday, April 23, but his cause of death remains unknown.

The Patriots released the following statement:

“We were deeply saddened to hear the news this morning of Ron Brace’s death. Seven years ago, we drafted Ron after his standout career at Boston College. During his Patriots career, the Springfield native was always eager to volunteer and give back in our communities, especially when those community initiatives were held in Western Mass. It is difficult to believe that someone so young and in the prime of his life is no longer with us. Our thoughts and prayers go out to Ron’s family, friends and the many former teammates who will mourn Ron’s passing.”
