Former NFL linebacker Grady Allen, the father of first-year Raiders coach Dennis Allen, died from heart complications on Monday night.

The Raiders said that Dennis Allen will return to the Bay Area on Wednesday night and will coach Oakland's home game Thursday night against the Denver Broncos.

Raiders offensive coordinator Greg Knapp and defensive coordinator Jason Tarver have been put in charge of game preparations this week.

"The organization wishes to extend its most sincere condolences to Coach and his entire family," the Raiders said on their Twitter account.

Grady Allen, 66, played for the Atlanta Falcons from 1968-72.

The Raiders are 3-9 under Dennis Allen, who served as the Broncos' defensive coordinator last season.
