ST. LOUIS (AP) -- The St. Louis Rams, next to last in offense in the NFL, have fired offensive coordinator Frank Cignetti.
Rob Boras, assistant head coach/offense and tight ends coach, will take over the coordinating duties.
St. Louis (4-8) has lost five in a row and had a season low for points in a 27-3 loss to the Arizona Cardinals on Sunday.
Both the 45-year-old Boras and the 50-year-old Cignetti had been with Jeff Fisher since the head coach was hired in 2012.
Cignetti was quarterbacks coach for three seasons and was promoted to offensive coordinator in February after Brian Schottenheimer became offensive coordinator at Georgia.
