St. Louis Rams coach Scott Linehan has been fired, two team sources said Monday morning.
Defensive coordinator Jim Haslett, a former head coach of the New Orleans Saints, was expected to be named interim coach, but details had not been finalized.
An official statement from the team around was expected for 8:30 a.m. ET.
The Rams dropped to 0-4 on Sunday with a 31-14 loss to the Buffalo Bills (4-0).
Linehan, 11-25 in his third season, last week was put on notice to make immediate improvements by owner Chip Rosenbloom.
After three blowout losses to open the season, Linehan benched quarterback Marc Bulger in favor of 38-year-old Trent Green. Linehan had six new starters in all, four on defense.
Rams running back Steven Jackson, who had criticized Linehan's decision to bench Bulger during his weekly radio show, had 110 yards on 24 carries and five catches for 78 yards.
