The Bills made another addition to their defensive staff, hiring Jacques Cesaire as their assistant defensive line coach.
Cesaire, 39, spent the last five seasons as the defensive line coach at the University of San Diego (2015-2019). A former NFL defensive lineman, Cesaire played nine seasons for the San Diego Chargers from 2003-2011 and appeared in seven career playoff games.
His most productive season as a player came in 2006 when he had career highs in tackles (37), tackles for loss (6), sacks (4.5) and quarterback hits (6).
Cesaire will assist new defensive line coach Eric Washington as they will both be in their first season on Buffalo's coaching staff.
Cesaire replaces former assistant line coach Aaron Whitecotton, who has reportedly accepted a coaching position with the San Francisco 49ers.
