UNDATED (AP) — Redskins quarterback Robert Griffin III says he's "ready to move on" and take a bigger role in practice as he works his way back from knee surgery. Griffin says he's had no soreness or swelling in his right knee during the first week-and-a-half of training camp.

Coach Mike Shanahan has limited Griffin to 7-on-7 drills during camp, keeping the quarterback away from 11-on-11 sessions. Griffin says he can only accomplish so much in the 7-on-7s and that he's ready for more.

Also in the NFL, Baltimore tight end Ed Dickson has a slight tear in his hamstring and will be sidelined for at least a week. Dickson had just 21 receptions last season after catching 54 passes for 528 yards and five touchdowns in 2011.

Green Bay starting left tackle Bryan Bulaga reportedly suffered a season-ending knee injury during a weekend scrimmage. The Journal Sentinel, citing an unidentified source, reported that Bulaga tore an ACL and will miss the season. The Packers canceled practice Monday and no one from the team was available to comment.

Denver tight end Joel Dreessen has undergone arthroscopic surgery on his left knee and is expected to miss the remainder of training camp. Right tackle Orlando Franklin limped off the field early during Monday's practice with an injured hip and did not return.

Browns running back Trent Richardson is in full pads and practicing again. The second-year pro was held out of Cleveland's two previous training camp sessions with a bruised right shin, but coach Rob Chudzinski said the move was strictly precautionary.

The Arizona Cardinals again were without their top two running backs as training camp resumed Monday following a day off for all the players. Rashard Mendenhall missed his third straight practice with patella tendinitis and Ryan Williams remained sidelined with a sore knee.

Colts receiver Darrius Heyward-Bey spent Monday afternoon watching Colts' practice due to a sprained knee. The team doesn't believe the injury is serious and expects Heyward-Bey to be back on the field soon.
