Mobile, Ala. — Lions secondary coach Marcus Robertson said he planned to interview to retain his job Monday or today.
He briefly spoke with new Lions defensive coordinator Teryl Austin Monday morning after weigh-ins at the Senior Bowl, but Robertson said a more thorough interview would follow.
Robertson said he’s still under contract with the Lions. He joined the team in 2012 as an assistant secondary coach, but was promoted this season after the Rams hired Tim Walton as defensive coordinator.
Robertson previously worked with the Titans secondary from 2007-11. He played safety 12 seasons, the majority with the Titans.
Although the Lions secondary struggled, particularly cornerback Chris Houston and at times safety Louis Delmas, young cornerbacks Bill Bentley, Jonte Green, Darius Slay and Chris Greenwood made strides.
New Lions coach Jim Caldwell has retained eight assistants from Jim Schwartz’s staff. Schwartz was fired Dec. 30 after a five-year record of 29-51.
Lions general manager Martin Mayhew said last week he hopes to fill the staff during the Senior Bowl.
In addition to a secondary coach, the Lions are still searching for an offensive coordinator and coaches for quarterbacks and wide receivers.
Three for the offensive line
As the coaching staff stands, the Lions likely will have three coaches working with the offensive line.
In addition to offensive line coach Jeremiah Washburn, Caldwell retained Bobby Johnson, who will move from tight ends coach to assistant offensive line coach. Johnson coached NFL and college offensive lines from 2005-11. Terry Heffernan’s title will change from assistant offensive line coach to offensive assistant, but he’ll work primarily with the line.
The Lions offensive line was one of the team’s strengths.
Center Dominic Raiola had arguably the best of his 13 seasons, and left tackle Riley Reiff played well in his second season. Right guard Larry Warford was considered by many the top rookie offensive lineman, and undrafted rookie free agent LaAdrian Waddle played well in eight starts.
The Lions allowed 23 sacks, second behind the Broncos (20).
Michigan offensive lineman Michael Schofield (6-foot-65⁄8, 303 pounds) played right guard the first day of the North team practice.
He started every game at right tackle the past two seasons, and also started 10 games at left guard in 2011.

“I’ve got to represent well and make Spartan Nation proud,” he said.
… Saginaw Valley State wide receiver Jeff Janis (6-2¼, 212) appeared to fit in with mostly FBS players on the North team and ran as a gunner on punt coverage. Janis drew the most attention when he suffered a big hit from a defensive back, though he popped right up.
