According to the Indianapolis Star's Stephen Holder, the Colts are indeed contemplating placing Arthur Jones on injured reserve with a designation to return.
Though we have yet to receive any sort of official update from the Colts regarding the status of injured defensive tackle Arthur Jones, all of the early indications are that it's not good. From Jones leaving the stadium in a walking boot on Saturday to ESPN's Josina Anderson reporting that Jones was seeing a specialist to Chuck Pagano saying that Jones is seeking a second opinion, it has become increasingly likely that Jones will miss significant time this year.
