The MRI determined the hit caused no further damage to Peyton Manning's tender right ankle.Now, Manning and the Broncos are curious what the NFL thinks of that hit.Interim coach Jack Del Rio said the Broncos have sent replays to the league offices of Corey Liuget's dive at Manning's ankles in the closing minutes of Denver's 28-20 win over San Diego."In the rules, there are certain areas you can hit and certain areas that are supposed to be protected," Del Rio said Monday. "And we thought that got into an area that was supposed to be protected."Manning, whose ankles have been hurting since games against Jacksonville and Indianapolis last month, stayed down after Liuget dove at him following a completed pass that iced the game with 1:44 left. Manning limped through the rest of the game and in the locker room afterward.An MRI on Monday showed no further damage to the ankle, which was heavily taped throughout the Chargers game. Del Rio said Manning would play next Sunday in Denver's AFC West showdown against Kansas City. The quarterback's practice schedule will be determined later in the week."But he'll definitely play this week," Del Rio said. "He's ready to roll and that's good news."Though it only lasted a brief moment, the sight of Manning wincing in pain on the ground served as a chilling reminder of how fragile Denver's season could be. Manning added four more touchdowns against the Chargers to bring his total to 33 on the season tied with Tom Brady for most through nine games in NFL history. But there's still validity to the point Broncos executive John Elway's made when he signed Manning two offseasons ago: "I don't have a Plan B. We're going with Plan A."On Monday, Del Rio was asked about Manning's backup, Brock Osweiler: "A good young player that is better in his second year than he was as a rookie. Continuing to develop. The arrow is up on him." Around the league Titans • Quarterback Jake Locker will miss the rest of the season with a Lisfranc injury to his right foot that may need surgery. Ryan Fitzpatrick replaces Locker with the Titans hosting Indianapolis on Thursday night. Jets • New York reinstated tight end Kellen Winslow Jr. to the active roster, and he will be available to play Sunday against the Buffalo Bills. Winslow was suspended by the NFL last month for violating the league's policy on performance-enhancing substances. Seahawks • Seattle added wide receiver Percy Harvin (hip) to the 53-man roster. Monday's move was expected as Seattle had to add Harvin to the active roster or he would have to remain on the physically unable to perform list for the remainder of the season. Seattle coach Pete Carroll said Harvin is expected to practice this week, meaning his Seahawks debut could come Sunday against Minnesota. If he's not ready, Harvin could be inactive on game day and his debut could come after the Seahawks' bye week when Seattle hosts New Orleans on Dec. 2.
