The Los Angeles Chargers filled out their coaching staff with the addition of four new assistants.
Head coach Anthony Lynn announced that 17 coaches from last season will return in addition to the newcomers, the team announced Tuesday.
Two of the coaches will help in the passing game -- wide receivers coach Phil McGeoghan and tight ends coach Rip Scherer.
McGeoghan spent last season as the wide receivers coach of the Buffalo Bills. He also served in the same capacity for four seasons with the Miami Dolphins (2012-15).
Scherer coached tight ends and was the associate head coach at UCLA the past two seasons. He also has served as quarterbacks coach in the NFL with the Carolina Panthers and Cleveland Browns.
Lynn's other additions were assistant special teams coach Keith Burns and defensive quality control coach Addison Lynch.
Burns is a former special teams coordinator with the Washington Redskins. Lynch spent last season at Florida State on the staff of former head coach Jimbo Fisher.
