Just might as well keep him and let him compete for a starting job next year or provide depth across the interior of the line.
Depends how much they like Dedich, who played well once he began playing. Plus of course Limmer and possibly even Leveston, and whether they like his potential.
If Jackdon just gets hurt again is it worth having him? They can save $3M of cap space if they cut or trade him.
Let's say they can get a 4th rd pick while giving back a 6th rd pick. That extra 4th, along with maybe a late 3rd, could be used to trade up for a player that might slip to the latter part of rd 2 or top of rd 3. Maybe you can get your future RT with that pick. Or maybe a CB they really like falls to late rd 2 or early 3.
So you could add $3M of cap space, rid yourself of an injury headache, and get some ammo to trade up or to just get a higher mid rd pick.
I wouldn't give him away for a 7th rd pick, but if you can get a little value for him, why not move him?
