METAIRIE, La. -- The New Orleans Saints brought back guard/center Eric Olsen on Tuesday -- a possible sign that they're expecting starting center Jonathan Goodwin to miss some time with an unspecified leg injury.

Olsen was with the Saints in 2012, playing in all 16 games and making four starts as an extra lineman. He lost his backup swingman job to rookie Tim Lelito last year, however, after being placed on injured reserve with an unspecified injury at the start of the 2013 season.

Olsen (6-foot-3, 305 pounds) caught on briefly with the Pittsburgh Steelers last season but didn't play in a game. He then spent this offseason with the Tennessee Titans before being released.

The 26-year-old was a sixth-round draft pick of the Denver Broncos out of Notre Dame in 2010. But he appeared in only one game with the Broncos before joining the Washington Redskins' practice squad and eventually landing in New Orleans.

Goodwin was carted off the field during New Orleans' 24-23 loss to the Detroit Lions this past Sunday. The severity of his injury is unknown -- though it could possibly be considered a good sign that he wasn't placed on injured reserve.

If Goodwin can't play, Lelito will continue to replace him in the starting lineup, which has been a smooth transition while Goodwin has missed time with a variety of smaller injuries this season.

The Saints had a vacant roster spot available for Olsen after placing defensive end Glenn Foster on injured reserve Monday and releasing linebacker Todd Davis. They used the other roster spot to sign tight end Tom Crabtree.

New Orleans also made a practice squad switch Tuesday, releasing center Alex Parson and signing offensive tackle DeMarcus Love.
