The Buffalo Bills are going to interview Cleveland Browns offensive coordinator Kyle Shanahan and San Francisco 49ers offensive coordinator Chris Roman..
Shanahan has been an offensive coordinator in the NFL for seven seasons.
He was previously the Washington Redskins and Houston Texans offensive coordinator.
Shanahan has never been a head coach.
Roman has successfully led the 49ers' offense, coaching quarterback Colin Kaepernick, running back Frank Gore, wide receivers Anquan Boldin and Michael Crabtree and tight end Vernon Davis.
The Bills need a new coach with Doug Marrone having opted out of his contract.
