Former Raiders standout running back Marv Hubbard has died after a long battle with prostate cancer, the Bay Area News Group has reported. He was 68.

The bruising fullback spent all but his last year with Oakland. He would have been on pace for four consecutive 1,000-yard efforts if the seasons in his era consisted of 16 games. As it was, he eclipsed that mark only in 1972.

Hubbard played eight years and finished his career with 4,544 yards rushing and 23 touchdowns on the ground. He was also an effective pass-catcher, snagging 85 for 628 yards and a score.
