PHILADELPHIA (973espn.com) - The Eagles have moved on from another assistant coach, parting ways with defensive line coach Phillip Daniels.

An NFL source confirmed the decision to 973espn.com and Daniels himself went to social media addressing his departure.

“Thank you to the Eagles organization for 4 great years,” Daniels wrote on Twitter. “I’m proud of what we accomplished as a DL and even prouder of what we accomplished this season against all odds. Thank you to Mr. Lurie and entire Eagles Org."

A 15-year NFL defensive end as a player Daniels finished his playing career in 2010 and spent a year with the Washington Redskins as Director of Player Development in 2012. From there Daniels decided his future was in coaching and began as a defensive quality-control coach and assistant defensive line coach for the Eagles in 2016. When Philadelphia moved on from Chris Wilson last year, Daniels was promoted.

The Eagles now have four open coaching positions on their staff to fill after moving on from offensive coordinator Mike Groh and wide receivers coach Carson Walch. Meanwhile, defensive backs coach Cory Undlin left to take the defensive coordinator position with the Detroit Lions.

Earlier Friday Baltimore coach John Harbaugh confirmed that Eagles asked to interview two of his assistants, QB coach James Urban and tight ends coach Bobby Engram. The Ravens granted permission but each decided to withdraw from any consideration in Philadelphia and return to Harbaugh's staff. Urban was being looked at for offensive coordinator and Engram as WR coach.

The Eagles are also reportedly interviewing Southern Cal offensive coordinator and QB coach Graham Harrell for the OC position, according to the Philadelphia Inquirer.

Harrell, a former backup QB with Green Bay and the New York Jets, is a Texas Tech product whose coaching experience has been limited to college thus far with stints at Oklahoma State, Washington State, and North Texas before being named OC at USC in 2019. He's known as an "Air Raid" coach from his time as a player and his stints at WSU and Southern Cal.
