The Bengals have for good severed ties with 2007 second-round draft pick Kenny Irons.  The team had put Irons on waivers, and though he cleared waivers the team has decided to release him instead of trying to put him on the PUP list.  Irons blew out his knee during a preseason game last season, and was trying to make it back.  The team will not have to pay his $370,000 salary in 2008.  He will make the $275,000 that was coming to him since the team cut him before he was fully healed from his injury from last season.
