Eric Mangini has been fired as defensive coordinator of the San Francisco 49ers.

Mangini had been with the 49ers organization for three seasons, but was the defensive coordinator for just one year. Mangini worked as a tight ends coach and offensive consultant under Jim Harbaugh in 2014 and 2013, respectively.

Mangini was previously a head coach with the New York Jets and Cleveland Browns.

Jason Tarver is a possible replacement for Mangini.
