It looks like the Dallas Cowboys' search for a defensive coordinator suffered another setback, with one of the candidates apparently deciding to take the same position with the San Diego Chargers.

Greg Manusky, who interviewed with the Cowboys on Wednesday, will instead head to the Chargers, according to the San Diego Union-Tribune. However, the deal isn't finalized.

Vic Fangio also met with Cowboys officials, but it appears he's leaning toward the San Francisco 49ers.

Miami Dolphins assistant coach Todd Bowles spoke to the Cowboys last week about their head coaching position before it was given to Jason Garrett. But Bowles hasn't been invited back despite being a defensive coach and knowing the Cowboys personnel, having coached here for a few years. The Cowboys would need permission again from the Dolphins to interview for the defensive coordinators position based on league rules.

Thursday, Paul Pasqualoni, who finished the season as Dallas defensive coordinator, left to become the head coach at the University of Connecticut.

There are two veteran coaches experienced in the 3-4 scheme who are available in Rob Ryan and Eric Mangini, but whether the Cowboys reach out to them is uncertain.

Todd Grantham, who is the defensive coordinator at Georgia, is a former Cowboys defensive line coach. He could come into play as well.
