Bills waived RB Anthony Allen.

A 2011 seventh-round pick of the Ravens, Allen was signed to a reserve/future deal in January. Allen has 19 career carries for 69 yards (3.6 YPC), but was out of the league last season.

Bills signed RB Anthony Allen, LB Kourtnei Brown and OG Randy Colling to reserve/future contracts.

A 2011 seventh-rounder, Allen appeared in 21 games for the Ravens between 2011-12, but was cut loose last August. Brown has never appeared in an NFL game. A former undrafted free agent out of small-school Gannon, Colling was a CFL standout.

Ravens waived RB Anthony Allen.

Allen's fate was sealed by the Ravens' acquisition of Delone Carter. A 2011 seventh-rounder out of Georgia, Allen was also waived at final cuts last season only to return and appear in all 16 games. He had a dud preseason, carrying the ball 20 times for just 68 yards (3.4 YPC).

Ravens signed RB Anthony Allen to a one-year, $555,000 exclusive-rights free agent tender.

Allen appeared in all 16 games last season, rushing 16 times for 61 yards with a touchdown while focusing on special teams. He'll battle for a roster spot in camp once again this year.

Ravens RB Anthony Allen and OL Gino Gradkowski have passed their baseline tests after suffering concussions at Denver last week.

Both players are now cleared to play in the AFC Championship game. Allen is a third-string running back and special teamer. Gradkowski is the heir to Matt Birk's center job.

Ravens waived RB Anthony Allen.

Allen, a 2011 seventh-rounder out of Georgia Tech, ran with the first-teamers for much of the spring. But when the pads went on, he was outclassed by Bernard Pierce and struggled in pass protection. Pierce and Bobby Rainey will continue to compete for snaps behind Ray Rice.

Ravens RB Anthony Allen has allowed a sack in each of Baltimore's first two preseason games.

Allen's struggles in pass protection won't endear himself to the coaching staff. Allen lost two yards on his lone carry in Friday's game, and muffed one of his three pass targets. He's rushed for seven yards on six carries through Baltimore's first two preseason games, adding one catch for 12 yards. Barring injury to Bernard Pierce, Allen will open the year third on the depth chart.

According to the Baltimore Sun, Ravens RB Anthony Allen "hasn't demonstrated much in the way of moves."

The Baltimore Sun believes it's "fair to say" Anthony Allen will open Ravens camp as the team's No. 2 tailback.

Allen worked with the first-team offense all spring while Ray Rice stayed away, and knows Cam Cameron's system better than rookie Bernard Pierce. Pierce, a third-round pick, remains the favorite for No. 2 back duties and will receive an "extensive" look this preseason. We prefer Pierce for Rice handcuffers.

Anthony Allen spent the majority of spring workouts with the first-team offense.

Third-rounder Bernard Pierce may have pushed Allen for first-team reps this week had he not tweaked his hamstring in Tuesday's practice. Allen will enter training camp as Ray Rice's primary backup, though Pierce has the talent edge to climb the depth chart by the end of preseason action.

Head coach John Harbaugh acknowledged that the Ravens will add a veteran running back at some point this offseason.

"Anthony Allen goes from third to potentially No. 1 if something happens," Harbaugh said. "We think a lot of him, but we've got to look at some insurance, too.'' The Ravens currently have only three running backs on the active roster, and franchise player Ray Rice has yet to sign his tender. Third-stringer Damien Berry went undrafted in 2011.
