Ryan Williams injury: Cardinals to 'keep an eye' on Tim Hightower

With the news that Cardinals running back Ryan Williams will be out for the season, Arizona may be looking at Tim Hightower as a possible replacement. The former Cardinals back was released by the Redskins in the preseason, and is currently injured, but Jason La Canfora of CBS reports Arizona is looking into the possibility of adding the fifth-year veteran:

For those who were asking about Tim Hightower before, sounds like he's 2 more weeks away from being healthy. I expect AZ to keep an eye out

Hightower played for the Cardinals from 2008 to 2010. In that time, he rushed for 1733 yards and 23 touchdowns on 429 carries. After playing in all 48 games at Arizona, Hightower had an injury-shortened season with the Redskins in 2011. He played in just five games, carrying 84 times for 321 yards and one touchdown.

Williams injured his left shoulder and will have surgery Tuesday. He was playing in place of Beanie Wells, who is suffering from a case of turf toe. Wells will not be eligible to play until Nov. 25. LaRod Stephens-Howling, William Powell, and Alfonso Smith may get carries in the meantime.
