WESTFIELD Peyton Manning Jersey , Ind. — Indianapolis Colts starting defensive end Jabaal Sheard missed practice again Saturday with an injured knee and it’s not clear when he could return.Coach Frank Reich told reporters Friday the team’s medical staff was evaluating Sheard’s knee for soreness and swelling.Reich did not speak following the team’s first workout in full pads, but team owner Jim Irsay says the injury is “not season-ending” and he expects Sheard to play this season.Sheard has started all 32 games since signing with the Colts in 2017, and finished sixth on the team in tackles with 50 and third in sacks with 5½ last season.Quarterback Andrew Luck, receiver T.Y. Hilton, left tackle Anthony Castonzo also sat out as part of scheduled rest days.52<button class="view-gallery">View Gallery</button> Gallery:Greetings from Westfield: Colts training camp 2019AP | Copyright The Associated Press.

The NFL might allow some of its young players to get experience by playing in the Alliance of American Football.Bill Polian Al Woods Color Rush Jersey , the Hall of Fame general manager and AAF executive, says he and some NFL colleagues have talked informally about whether certain young players could play in the AAF during the NFL offseason.“The talk is ramping up – I’ll say that,” Polian told .It could make sense for the NFL to assign some players who haven’t had much playing time to the AAF to help them gain additional experience. Young quarterbacks in particular might be able to improve with AAF playing time — and for those who don’t improve, it at least alerts their NFL teams not to count on them in the fall.It’s unclear whether the NFL Players Association would approve of such an idea. When the current Collective Bargaining Agreement was negotiated, the players got a reduced offseason workload. The union might not agree to allow players to spend three months in the AAF during the offseason. Then again https://www.coltsfanshop.com/Erik-Swoope-Jersey , those players would be collecting an additional salary from the AAF, which the union might view as worth it.“Those discussions will continue but whether they bear fruit remains to be seen,” Polian said. “There are lots of procedural hurdles that have to be crossed before you could make that happen.”The AAF has been careful to make clear that it is not competing with the NFL and actually wants to solidify its relationship with the NFL. Next year, that might even include some NFL backups on the field in the AAF.
