Alex Anzalone's promising rookie season was cut short by a shoulder injury that required surgery, according to Saints coach Sean Payton.

The Florida product started the first four games at weak-side linebacker before suffering the injury on the third snap against Miami. 

New Orleans placed him on injured reserve three days later, and according to Payton, surgery to repair the shoulder was successful.

"We felt like he had gotten off to a real good start," Payton said. "I know his surgery went well, and it was disappointing because he had really started well as a first-year player."

Anzalone had 15 tackles, a sack and a pass defended in three games. Without him in the lineup, veteran Craig Robertson took the snaps at weak-side linebacker the rest of the way against the Dolphins and likely becomes a starter again now.

"The other guys are going to step up," Payton said. "I'm not going to go through who's playing where and what personnel groupings."
