He appeared at camp out of shape and was sent home. Last I heard, he is supposed to return to action with Hamilton within the next few weeks. If you don't mind digging through a load of posts about other topics, check the Hamilton/Cincinnati thread stickied on the main board here.
EDIT - Found the link that mentions his status. It doesn't actually mention a return timeframe, just he is getting himself sorted. Its near the bottom. This is the link (save you searching through the other thread)
