Oregon desperately needs to develop wide receivers to replace Dillon Mitchell’s production next season.

Michael Johnson Sr. will not be leading the effort.

After two seasons as the Ducks’ wide receivers coach, Johnson is leaving the Oregon coaching staff to take the same position at Mississippi State, according to a 247Sports report.

Mario Cristobal is in the market for a new assistant for the second time this offseason, having already replaced outside linebackers coach Cort Dennison, now at Louisville, with Washington State’s Ken Wilson.

Dennison had a $275,000 salary during his one season at Oregon. Wilson signed a three-year contract with an annual guaranteed salary of $350,000.

Johnson’s salary at Oregon was $335,000. His son, Michael Johnson Jr., signed with Penn State in December after quarterbacking Sheldon High to the OSAA 6A state title game.

Last year under Johnson’s tutelage, Mitchell led the Pac-12 and set a single-season Oregon receiving record with 1,184 yards and 10 touchdowns. The junior decided to enter the NFL draft instead of exhausting his collegiate eligibility.

The Ducks return three players with starting experience — Jaylon Redd (433 yards, five touchdowns), Johnny Johnson (215 yards, four touchdowns) and Brenden Schooler (203 yards, one touchdown).

Bryan Addison, a 6-foot-5 freshman who retained his redshirt after playing in only four games in 2018, and true freshman Josh Delgado, a member of the touted 2019 recruiting class who is on campus, will also compete for a starting role during spring practice.
