"I don't have a lot of details," coach Jon Gruden said after practice. "It's just a horrible tragedy, and I can't explain it."

Bryant, a seventh-year pro in his fourth season with Tampa Bay, kicked a winning field goal in overtime against Chicago last Sunday. Two years ago, he made the third-longest field goal in NFL history, a 62-yarder to beat Philadelphia.

"The entire Buccaneer family is deeply saddened by this tragedy," general manager Bruce Allen said in a team statement.

"The Bryants have been an inspiration to our entire community through their commitment to their family and their exhaustive efforts working with children and those in need in the Bay area. Our thoughts and prayers are with Matt and Melissa during this difficult time."
