ORCHARD PARK, N.Y. — Bills quarterback EJ Manuel returned to practice Sunday after missing two weeks for left knee surgery.
The former Florida State standout, drafted 16th overall in April, had been out since getting hurt in the second preseason game. He had what the team called only a "minor procedure" Aug. 18.
"He looked good," Bills coach Doug Marrone said. "If we can have him practicing on Wednesday and we feel that he's good enough and mentally ready to play, then he's going to play (in the season opener Sunday)."
The only other quarterback is undrafted rookie Jeff Tuel.
"I just really want to see how it reacts (today) as far as the soreness," Manuel said. "I don't think I'll have any soreness because I didn't have any after I ran around and threw the other day."
More Bills: Safety Jairus Byrd, who didn't sign a franchise player tender until Aug. 20 and has practiced little because of a sore foot, said he was diagnosed with plantar fasciitis. His status for the opener hasn't been determined.
Gronkowski back: New England tight end Rob Gronkowski took part in his first full-pads practice since June's back surgery. The Patriots put him on the active roster instead of the physically unable to perform list, which requires a six-game absence. Coach Bill Belichick hasn't said when Gronkowski will play, but it's unlikely to be in Week 1. Also, former FSU kick returner Leon Washington was released.
Browns: Tight end Kellen Davis, who started 15 games last season, was released.
Chiefs: Former Florida receiver Frankie Hammond was signed to the practice squad.
Colts: Linebacker Daniel Adongo was signed to the practice squad. The rugby player from South Africa had never played football before camp.
Falcons: Eight players were signed to the practice squad but not linebacker Brian Banks, who was cut Saturday. He is trying to launch his career after spending five years in prison on a rape conviction that was overturned.
Jaguars: Former FSU fullback Lonnie Pryor was released.
Packers: Quarterback Scott Tolzien, who spent the past two seasons with the 49ers, was signed to the practice squad. Green Bay faces the 49ers in Week 1.
Raiders: Punter Chris Kluwe, 31, was released in favor of undrafted rookie Marquette King and said he agreed. "As the young guy, he definitely has the higher potential ceiling," he said in a text message to USA Today. "It makes sense."
Titans: Linebacker Jonathan "Tig" Willard, who helped rescue a woman and her children from a burning car on his way to camp, was signed to the practice squad.
Vikings: Tackle J'Marcus Webb, who started 44 games over the past three seasons, was claimed after being waived by the Bears. Also, former FSU defensive tackle Everett Dawkins was signed to the practice squad.
Youngest team: For the second year in a row, the Rams will begin the season with the youngest roster. Their 53-man roster has an average age of 24.98. St. Louis has 29 players with two years or fewer of experience, including 12 rookies, and five players 30 or older.
