Gophers football coach P.J. Fleck on Thursday officially announced additions and assignments to his coaching staff.

The additions are Marcus West as defensive line/pass rush specialist coach and Jahmile Addae as defensive backs coach. The new assignments are Brian Callahan, who coached Minnesota’s tight ends last year, to offensive line coach, and Clay Patterson, who was hired in January, as tight ends coach. Also, Daniel Ifft, a recruiting assistant last year, was named director of football operations.

West joins the Gophers after spending the past two years as assistant head coach, defensive coordinator and defensive line coach at Austin Peay. He helped the Governors post an 8-4 record in 2017 after they were a combined 1-45 from 2013-16. Austin Peay went 8-1 against fellow FCS-level programs last year. Three of its losses were against FBS schools Cincinnati, Miami (Ohio) and unbeaten Central Florida. West replaces Bryce Paup, who reportedly left to pursue an NFL opportunity and no longer is listed on Minnesota's coaching staff.

Addae was Arizona’s defensive backs coach the past two seasons after serving as an analyst for the Wildcats in the previous three seasons. Arizona had 19 interceptions and 49 pass break-ups last season. Addae replaces Maurice Linguist, who left to become Texas A&M’s cornerbacks coach.

Callahan was Fleck’s offensive line coach at Western Michigan from 2013-16 and helped the Broncos to a 13-1 record and Cotton Bowl berth. Western Michigan averaged 41.6 points, rushed for 3,392 yards and 36 touchdowns and passed for 3,533 yards and 33 TDs with only 16 sacks allowed. Callahan replaces Ed Warinner, who left to become a senior offensive analyst at Michigan.

Patterson comes to Minnesota after being the head coach at Northeastern Oklahoma A&M the past two seasons. The Norsemen improved from 5-5 in 2016 to 9-3 with a conference championship last year.
