Running back C.J. Spiller, expected to be the central weapon in the Buffalo Bills' offense this season, has left the team to be with his family in Florida after the suicide of his step-grandfather, Hubert Allen, Jr.
Allen Jr. allegedly killed two people and shot two others before killing himself on Saturday.
"I talked to him when we landed from the Washington game," Marrone said, according to CBS Sports. "I obviously excused him to be able to go back and handle obviously what is a personal situation. Our thoughts and prayers go out to the victims as well as C.J. and his family in this situation. ...We're in communication just making sure that we're there to support him."
