The Bills have provided themselves with some immediate security should another defensive back go down to injury. The club signed Dustin Fox to the team's practice squad Wednesday morning.
Fox originally joined the Bills last year on Sept. 19 and spent eight weeks on the team's practice squad before being promoted to the 53-man roster for the final six weeks of the season. He was with the Bills throughout training camp and was released prior to the start of this season.
With Ashton Youboty moved to the injured reserve list last week, Buffalo has just four cornerbacks on their active roster. Safety Donte Whitner can be used as an emergency cornerback, but he has also been on the shelf with a separated shoulder.
Fox, offers depth at both safety and cornerback and was used at both positions in training camp this past summer.
Originally drafted in the third round of the 2005 NFL Draft by the Minnesota Vikings, he spent the '05 season on injured reserve. Fox appeared in one game for the Philadelphia Eagles in 2006 and has played in seven games in his career.
To make room for Fox on the eight-man practice squad, the Bills released offensive lineman Chris Denman.
