AFC West notes

The Indianapolis Star is reporting that Peyton Manning has been throwing better. Manning could be cut by the Colts within the next six days since he's owed a $28 million roster bonus on March 8. If he becomes available, the Chiefs will monitor his progress.

The Football Outsiders believeInsider San Diego free-agent receiver Vincent Jackson would be a perfect fit in Chicago to team up with former AFC West rival Jay Cutler.

Raiders running back Michael Bush is likely on the way out in free agency. One possible destination to keep an keep an eye on: Cincinnati. The Bengals are expected to pursue a running back.

The Steelers cut Chris Kemoeatu. He is a massive guard who could attract interest from the Chargers if they decide to go the free-agent route to replace the recently retired Kris Dielman. Kemoeatu has been injury-plagued and his level of play has gone down some. The Chargers may opt to give backup Tyronne Green a chance to start.
