A highly placed league source outside the Sharks’ organization confirmed Thursday that Doug Wilson’s job as San Jose’s general manager is “100 percent safe” despite the team missing the postseason for the first time in 11 seasons.

A letter sent to Sharks season-ticket holders from owner Hasso Plattner would appear to support the source.

In the letter, Plattner said, “The management, (chief operating officer) John (Tortora) and Doug (Wilson), did a good job.”

Plattner also raises a couple of red flags — the team’s frustrations over its television contract and its continued dealings with the city of San Jose to get a new lease for SAP Center.

Wilson had said Monday, after it was announced that the team and coach Todd McLellan were “mutually parting ways,” that he had yet to meet with Plattner.

Wilson, 57, was named general manager on May 13, 2003, after serving as the team’s director of pro development since 1997. The Sharks reached the playoffs in Wilson’s first 10 seasons as GM, what had been the third-longest active streak in pro sports behind those of the Detroit Red Wings (24) and NBA’s San Antonio Spurs (18).
