2,000 yards passing/2,000 yards rushing

Submitted by jb5O4 on

I know that 2,000 yards rushing for Denard is going to be a tough feat to get  (he'll have to average 157 yards per game the rest of the season). But I was trying to find if any quarterback had rushed for 2,000 yards and passed for 2,000 yards in the same season.
