The Saints made a number of roster moves Wednesday.

The team placed running back Marcus Murphy (ankle) and cornerback Damian Swann (concussion) on injured reserve and signed running back Kendall Hunter and cornerback Tony Carter.

The Saints also promoted fullback Toben Opurum from the practice squad and signed wide receiver Shane Wynn to take his place.

Hunter was released by the San Francisco 49ers with an injury settlement in September. He was working his way back from a torn ACL.

Serving as Frank Gore’s backup in San Francisco, Hunter, 27, rushed for 1,202 yards on 262 carries (4.6 yards per attempt) and seven touchdowns between the 2011-2013 seasons. He also caught 27 passes for 268 yards and returned a handful of kicks.

In New Orleans, the 5-foot-7, 199-pound Hunter joins Tim Hightower and C.J. Spiller in the backfield. Along with Murphy, Mark Ingram (shoulder) and Khiry Robinson (leg) are on injured reserve.

Carter, 29, was most recently with the Colts, appearing in three games this season. He previously played for the Denver Broncos (2009, 2012-2014) and New England Patriots (2010).

Carter (5-9, 175 pounds) has three career interceptions.

Murphy suffered a high-ankle sprain during Sunday’s win over the Tampa Bay Buccaneers. It was not considered serious, according to a source, but he was expected to miss at least two weeks. Given how late it is in the season, New Orleans decided to place him on injured reserve.

Swann suffered his third concussion of the season against Tampa Bay, according to a source.

Opurum becomes the second fullback on the 53-man roster after Austin Johnson was called up from the practice squad last week.
