The Ravens, who are finishing their 20th season in Baltimore, now have 20 players on season-ending injured reserve.
They reached that number on Tuesday, when they officially placed wide receiver Marlon Brown on I.R., ending his disappointing season. The Ravens promoted defensive back Sheldon Price from the practice squad to the active roster to take his place.
The 20 players on injured reserve are the most during coach John Harbaugh's eight-season tenure. That list doesn't include rookie linebacker Brennen Beyer, who is on practice squad/injured reserve, or tight end Dennis Pitta, who remains on the physically unable to perform list.
Brown, who was expected to be a key contributor on offense, finishes the year with just 14 catches for 112 yards and no touchdowns. Eleven Ravens have had more receptions than Brown did this season.
The third-year pro goes on injured reserve after missing the previous five games with a back injury.
"Marlon is one of my favorite guys, and he works really hard at it, has a great attitude and, to my eyes, is very talented," Harbaugh said Monday. "But, it just hasn't worked in the last two years like we all expected after his rookie year, especially how Marlon expected to continue to improve. It's going to be a really important offseason for him, and it's going to be a critical season for him when he comes back."
An undrafted player out of the University of Georgia, Brown had 49 receptions for 524 yards and a rookie franchise-record tying seven touchdown receptions in 2013. However, in the past two seasons, he's totaled 38 catches for 367 yards and no touchdowns.
Brown, 24, is a restricted free agent after the season and the Ravens might choose not to tender him a contract.
Price, who was signed to the Ravens practice squad in late October, played in two games for the Indianapolis Colts this season.
