The Bears reportedly worked out former Packers running back Ryan Grant on Tuesday.  The Notre Dame product, who spent five seasons with Green Bay, has rushed for over four-thousand yards and 25 touchdowns in his career.  The Bears could use some depth at the running back position with Matt Forte [[ for-TAY ]] out with an ankle injury and backup Michael Bush a little banged up during Week Three's win over St. Louis.  Chicago plays at Dallas in Week Four on "Monday Night Football."
