That's been out of necessity though - the squad is full of good CB's but injuries have meant holes in the team that Jones is able to fill.
He's also looked very slightly green at CB so I imagine that SAF is in no particular hurry to play him there at this point and content to give him playing time at United elsewhere in the team.
