A week after Jim Tomsula was introduced as the San Francisco 49ers' 19th head coach in franchise history, the team has yet to fill openings at offensive coordinator, defensive coordinator and special-teams coach.
There has been movement at other positions, though.
Here is a tracker of assistants linked to Tomsula's staff:
Offensive coordinator -- Lane Kiffin is a "front-runner" for the position. Rob Chudzinski, Mike Shanahan and Marc Trestman were also linked, though Trestman was hired as Baltimore's coordinator and the Indianapolis Colts are reportedly blocking teams from interviewing Chudzinski. Niners QB coach Geep Chryst is considered an option.
Offensive line coach -- Chris Foerster, the Niners’ O-line coach in 2008 and 2009, is reportedly returning to same position.
Assistant offensive line coach -- Eric Wolford purportedly is joining Foerster.
QB coach -- Chryst, the Niners' QB coach since 2011, is reportedly set to return, though in what capacity is not yet known. He was linked to Chicago Bears' coordinator position before they hired Adam Gase.
Tight ends coach -- Former Oakland Raiders interim head coach Tony Sparano is set to come down I-880.
Running backs coach -- Tom Rathman is reportedly set to return in the same capacity.
Offensive assistant -- Ronald Curry, with the Niners since 2013, was wooed by Buffalo, though the Niners reportedly denied the Bills permission to interview him.
Special-teams coordinator -- Former New York Jets special-teams coach Thomas McGaughey is linked to Niners’ opening after Brad Seely, released by Niners, was hired by Oakland Raiders for the same position. McGaughey worked with Tomsula in NFL Europe.
Defensive coordinator -- The 49ers were denied permission by Cincinnati to speak with Bengals secondary coach Vance Joseph, whose NFL coaching career began with Niners as a secondary coach. The Niners also considering former tight end coach Eric Mangini, a defensive mind who was New England Patriots’ coordinator in 2005 and head coach of the New York Jets (2006-08) and Cleveland Browns (2009-10).
Senior defensive assistant/linebackers -- Former Oakland Raiders defensive coordinator Jason Tarver was hired for the job. He ran a 4-3 defensive scheme in Oakland but is a 3-4 strategist at heart.
