With over half the NFL taking a day off from practice, it was a rather low-key news day around the league's training camps on Sunday. In a camp week filled with key injuries, no news equals good news for most teams.

Here's a rundown on some of the news and notes that did come out of Sunday's practices.

AFC East

Buffalo Bills - Rookie quarterback E.J. Manuel had a particularly rough day on the practice field, throwing at least three interceptions and missing several open receivers. With Kevin Kolb sidelined with a knee injury, Manuel took the majority of the first-team snaps, but seems to have missed an opportunity to pull ahead in the competition for the starting job. All that said, Manuel is only one week into his first NFL training camp, and apparently faced some complex looks from the Bills defense on Sunday.

Miami Dolphins - The Dolphins took part in Sunday night's Hall of Fame Game preseason opener, falling to the Dallas Cowboys 24-20. Quarterback Matt Moore was sharp in a reserve role, going 19-29 with 238 yards, one touchdown and one interception.

New England Patriots - The Patriots did not practice on Sunday.

New York Jets - The Jets did not practice on Sunday.

AFC South

Houston Texans - The Texans did not practice on Sunday.

Indianapolis Colts - It was a tough day for wideout Reggie Wayne, who reportedly had a severe case of the drops. On the other hand, it was good practice for former Ole Miss cornerbacks, as Marshay Green and Cassius Vaughn each had an interception.

Jacksonville Jaguars - The Jaguars did not practice on Sunday.

Tennessee Titans - The Titans did not practice on Sunday.

AFC North

Baltimore Ravens - Offensive lineman Ramon Harewood returned to practice on Sunday after missing the past week of practice with swelling in his surgically repaired knee. It wasn't all good news though, as safety James Ihedigbo and wide receiver David Reed both sat out with undisclosed injuries.

Cincinnati Bengals - It was a relatively uneventful day at Bengals camp, where players went padless and mostly participated in positional drills. Quarterback Andy Dalton seems to be developing connections with wideout Brandon Tate and tight end Tyler Eifert, both of whom stood out during 11-on-11 drills. That's good news for the Bengals, who announced Sunday that star receiver A.J. Green's knee injury will keep him out of the team's preseason opener.

Cleveland Browns - The Browns did not practice on Sunday.

Pittsburgh Steelers - Coach Mike Tomlin came up with a unique way to tell us that 32-year-old safety Troy Polamalu had earned a day off, stating the veteran was sitting out with a "contusion to the birth certificate." Aside from being old enough to draw barbs from his 41-year-old head coach, there doesn't appear to be anything significant about Polamalu's absence from practice.

AFC West

Denver Broncos - The Broncos did not practice on Sunday.

Kansas City Chiefs - While Jon Baldwin has been the No. 2 receiver opposite Dwayne Bowe for most of camp, Donnie Avery took over that role on Sunday, suggesting a possible shakeup on the depth chart. Tyler Bray showed off his strong arm during practice and seems to have taken firm control of the third-string quarterback spot.

Oakland Raiders - Injuries are mounting at Raiders camp, where 20 players sat out of practice on Sunday. While corner Brandian Ross made his return, starting corners Tracy Porter and Mike Jenkins joined the list of nonparticipants.

San Diego Chargers - The Chargers did not practice on Sunday.

NFC East

Dallas Cowboys - The Cowboys knocked off the Dolphins, 24-20, in the Hall of Fame Game to start the preseason. Starters saw limited action, and quarterback Tony Romo sat the game out altogether as he eases back from a May surgery to remove a cyst in his back.

New York Giants - The Giants shook up their first team offense during their full pads practice, giving starting snaps to several players who had worked exclusively as backups up until this point. Defensive tackle Shaun Rogers, linebackers Jacquain Williams and Dan Connor and right tackle James Brewer all got a handful of first-team reps during practice.

Philadelphia Eagles - Quarterback Michael Vick continued to strengthen his place atop the depth chart with a strong showing, while Nick Foles threw two picks during scrimmages. In injury news, both offensive tackle Jason Peters and running back Matthew Tucker left practice early with hamstring issues.

Washington Redskins - The Redskins did not practice on Sunday.

NFC South

Atlanta Falcons - The Bengals will be bringing cameras for HBO's Hard Knocks along with them when they visit Falcons camp next week for a combined practice, and we learned Sunday that Atlanta receiver Roddy White is no fan of the added attention. White is concerned the filming could expose parts of the team's offensive game plan, telling the Atlanta Journal-Constitution that "I don't want everybody to know the plays that we're running."

Carolina Panthers - The Panthers did not practice on Sunday.

New Orleans Saints - The Saints did not practice on Sunday.

Tampa Bay Buccaneers - The Buccaneers did not practice on Sunday.

NFC North

Chicago Bears - The Bears did not practice on Sunday.

Detroit Lions - All-Pro wideout Calvin Johnson had the day off, and second-year man Patrick Edwards filled in for him on the first-team offense.

Green Bay Packers - The Packers did not practice on Sunday.

Minnesota Vikings - The Vikings did not practice on Sunday.

NFC West

Arizona Cardinals - The Cardinals did not practice on Sunday.

Seattle Seahawks - Receiver Early Doucet, who signed with Seattle on Friday, was on the practice field with his new team for the first time on Sunday, though he was limited in his number of reps. With starter Percy Harvin's return from hip surgery still uncertain, Doucet adds much needed depth at the position.

San Francisco 49ers - The Niners got a boost to their injury-wracked receiving corps as recent signees Austin Collie and Lavelle Hawkins got on the field to work through passing drills with Colin Kaepernick. Defensive end Justin Smith sat out for a second consecutive practice, though there have been no indications of a significant injury.

St. Louis Rams - The Rams did not practice on Sunday.
