The San Diego Chargers agreed to a two-year deal with Greg Maunsky to become the team's defensive coordinator, the team announced Friday.
Manusky spent the last four years as the San Francisco 49ers' defensive coordinator.
"I'm excited about adding Greg to our staff," San Diego head coach Norv Turner said in a statement released by the team. "... He brings energy and enthusiasm and he'll be extremely demanding."
Manusky has 10 years of NFL coaching experience, including a five-year stint as linebackers coach for the Chargers from 2002-06, and is familiar with the 3-4 defense.
"Greg is very familiar with what we do [on defense]," Turner said. "He's been a coordinator in this league for the past four years, making game-play decisions during the week and making game-day decisions, and has done it at a high level."
While in San Diego in 2006, Manusky's linebacker unit accounted for 42.5 of San Diego's 61 regular-season sacks. San Francisco's defense did not allow a touchdown in five separate games in 2009 under Manusky and forced an NFL-best 21 fumbles.
Manusky, a former NFL linebacker, has seen several of his players earn Pro Bowl honors, including linebacker Patrick Willis, defensive tackle Justin Smith and cornerback Walt Harris with the 49ers, linebackers Shawne Merriman, Donnie Edwards and Junior Seau with the Chargers, and linebacker LaVar Arrington with the Redskins.
