The San Diego Chargers have re-signed defensive coordinator John Pagano, a league source told ESPN NFL Insider Adam Schefter.
Pagano, whose previous contract expired after this season, had drawn interest from the Tennessee Titans, according to the source.
The Chargers retained Pagano on Tuesday, one day after former San Diego offensive coordinator Ken Whisenhunt was hired to be the Titans' head coach. Tennessee will formally introduce Whisenhunt on Tuesday.
Pagano, the brother of Indianapolis Colts head coach Chuck Pagano, has worked on San Diego's coaching staff since 2002 and was promoted to defensive coordinator in 2012.
Pagano oversaw a defense this season that was instrumental to the Chargers' December surge to the postseason. After upsetting the Cincinnati Bengals in the AFC wild card round, San Diego was eliminated by the Denver Broncos in Sunday's divisional playoff game.
