The Cincinnati Bengals and Philadelphia Eagles have coaching staff openings to fill.

NFL Network reported Thursday that the Bengals will not bring back receivers coach Bob Bicknell, offensive line coach Jim Turner and defensive line coach Nick Eason. Running backs coach Jemal Singleton is leaving to accept a job at Kentucky.

In Philadelphia, senior offensive assistant Rich Scangarello and senior offensive consultant Marty Mornhinweg have contracts that are expiring and will not return, ESPN reported. Defensive coordinator Jim Schwartz previously said he will sit out the 2021 season as his contract also is expiring.

Bengals owner Mike Brown gave head coach Zac Taylor his endorsement on Monday, despite a 4-11-1 record in 2020.

“We remain bullish on the foundation Zac is building, and we look forward to next year giving our fans the winning results we all want,” Brown said in a statement.

Doug Pederson is expected to return for a sixth season in 2021, despite his team’s 4-11-1 record.
