The Lions have released Kevin Jones.

He's had two big injuries in the last two years (Lisfranc and ACL) and may not be ready for the start of the season. But when healthy he is a force, and he should come cheap at this point (if he doesn't, then obviously he's not an option). Keith/draft pick aside, anybody think he might be worth looking at? He's got good hands, and if he can have success behind the Lions line, then he should excel behind the Colts line.

I really don't know a lot about him, and I'm certainly not sold on him. But if he has a reasonable chance of regaining his health, he could be a valuable backup for a couple of years. And of course the flip side to the negative of the injuries is that he has a little less mileage on him.
