The Vikings’ longest-tenured assistant coach is moving on.

The Sporting News reported Monday that George Stewart, Minnesota’s wide receivers coach the past 10 seasons, will become the Los Angeles Chargers’ special teams coordinator under recently named head coach Anthony Lynn.

Stewart joined the Vikings in 2007. Mike Zimmer kept him on staff after taking over as head coach in 2014. During Zimmer’s tenure, Stewart played a role in the development of Minnesota wide receivers Stefon Diggs and Adam Thielen, who both had more than 900 yards receiving in 2016.

Stewart has ample experience coaching special teams. After entering the NFL in 1989, he spent 11 seasons coaching those units for Pittsburgh, Tampa Bay and San Francisco.
