Colts facing division leaders Monday

Peyton Manning isn't calling Monday night's showdown at Tennessee a must-win game, although that's exactly what he says the Indianapolis Colts need to do.

Already three games behind the AFC South-leading Titans, the NFL's only unbeaten team, another loss would just about kill any chance for a sixth straight division title for the Colts. Manning says he doesn't know what label to put on the game ... but he does know the team needs to win.

The Colts' 3-3 start is their worst in Tony Dungy's seven seasons as coach. The Colts made two roster moves Thursday, releasing cornerback Keiwan Ratliff and re-signing cornerback Nick Graham, who was cut last week. Ratliff had been the team's primary punt returner, but with his departure, rookie receiver-kickoff returner Pierre Garcon will also handle punts.
