Lions free agent Jason Fox visits Chiefs

The Detroit Lions have seven unrestricted free agents who have not been re-signed or signed by another team. Five of them have already been told that they won't be back in Detroit next season, leaving cornerback Rashean Mathis and offensive tackle Jason Fox as the only two UFAs who could be back.

Last week, we found out that the Lions were in talks with Mathis about a potential new deal, but there continued to be no developments on the Fox front. That changed on Monday, as Fox is reportedly visiting the Kansas City Chiefs.

So far, the Lions haven't expressed any public interest in re-signing Fox. He wouldn't be a bad backup option if they can get him back on a cheap deal, but considering how many injury issues he's had since joining the Lions in 2010, perhaps they have simply decided to move on. Fox did make three starts last year at right tackle, but he ended up losing the starting job to LaAdrian Waddle because he couldn't stay healthy.

If the Lions don't bring back Fox, look for them to either draft someone or sign a free agent (perhaps an undrafted free agent) to serve as extra depth at offensive tackle. Currently, the Lions have only Riley Reiff, Waddle and Corey Hilliard at the position, and they could use one more tackle to round out the two-deep.
