Jabari Greer on Tuesday officially joined the lengthy list of New Orleans Saints defensive players who have suffered a season-ending injury. The Saints placed Greer, their starting cornerback, on injured reserve, two days after he tore his left ACL against the San Francisco 49ers.

Greer had to be carted off the field Sunday after landing awkwardly while leaping to break up a pass.

Defensive end Kenyon Coleman, cornerback Patrick Robinson, and linebackers Will Smith and Jonathan Vilma are also on injured reserve. Linebacker Victor Butler tore his ACL in June and has been on the physically unable to perform list all season.

Under new defensive coordinator Rob Ryan, the Saints have withstood all the injuries and become one of the most improved defenses in the NFL. Greer, in his 10th NFL season and his fifth with the Saints, was one of the mainstays.

"Jabari is having such a great year," Ryan told reporters Tuesday, according to the New Orleans Times Picayune. "He's a great person. We'll miss him in the locker room most. He was having a great year. He was doing everything we asked him to do and then some."
