The father of Oakland Raiders head coach Dennis Allen has died, the team announced via its Twitter feed on Tuesday.
Grady Allen had been ill and his son had left the team to be with him yesterday.
Dennis Allen still plans to return and coach the Raiders in Thursday night's game against the Denver Broncos.
Our thoughts and prayers go out to the family of Grady Allen at this time.
