It does seem odd bringing him back to play reserves and take a spot which would have been filled with one of the clubs up and coming players. Unless we have some injury concerns and need him to avoid risking someone else? who knows ...
Scott, Sao, Ashworth all out injured for likely a couple of months each, which likely explains why Okunbor is back. He might be rubbish but we've just lost 3 players for a significant portion of the remaining season, we need bodies.
