Bush wrote in his blog for the Detroit club's official website: "Running the ball will be even more critical this week since it's a road game. The crowd is going to be loud, and if you run the ball physically and are gaining positive yards, it takes the crowd out of it a little bit.
"I do think this game is going to be a lot tougher for us to run the ball, but I think if we don't get frustrated early and just keep at it and stay positive, the big plays will come. I am looking forward to this game being a tough, physical running game."
Arizona allowed just 67 yards against the run last weekend.
