Unger has elected to retire from the NFL, Field Yates of ESPN reports.

EDGE Analysis

Unger's departure leaves a major void in the middle of the Saints offensive line, as the veteran center played more than 1,000 snaps last season. He finishes a 10-year career having been selected to three Pro Bowls and was donned a First-Team All-Pro back in 2012.

Unger (concussion) does not have an injury designation for Sunday's game against the Steelers.

EDGE Analysis

Unger sustained a concussion during Monday's win over the Panthers, but has managed to clear the league-mandated concussion protocol in time so play versus the Steelers. The veteran center will slot into his usual starting role.

Unger (foot) will open training camp on the physically unable to perform list, Josh Katzenstein of NOLA.com reports.

Unger (foot) is hopeful to be ready for action in Week 1, Josh Katzenstein of The Times-Picayune reports.

EDGE Analysis

Unger suffered a Lisfranc injury in Week 13 of last season. The original plan was to simply allow it time to heal, but he ultimately ended up having surgery in May. It is doubtful he participates in any preseason games, but his goal is to be ready for the start of the season.

Unger (foot) is now expected to return during the preseason, Mike Florio of NBC Sports reports.

EDGE Analysis

This is in stark contrast to recent reports from Ian Rapoport of NFL Network that Unger would be on the Physically Unable to Perform list at the start of the regular season after undergoing foot surgery last weekend. Unger's return to action prior to the regular season commencing would be a huge turn of events for the Saints, as he is a leader along the offensive line and they lack depth along the interior portion of their front five.
