One day after Syracuse bolstered its passing game by signing five athletic receivers in its Class of 2014, it lost its wide receivers coach.

Rob Moore, who spent the last four seasons with the Orange, was hired by the Buffalo Bills to fill the same position, the Bills announced Thursday morning. He becomes the sixth Doug Marrone assistant to follow the former SU head coach to “Syracuse West,” and will work under offensive coordinator Nathaniel Hackett again.

“We celebrate Rob Moore’s opportunity to coach in the National Football League with the Buffalo Bills and look forward to recruiting the next best person to help our program attack the Atlantic Coast Conference in 2014,” SU head coach Scott Shafer said in a statement. “We have communicated our plan with our team and our National Letter of Intent signees. As soon as we hire our new coach, we look forward to introducing him to Cuse Nation.”

Shafer said in a radio interview with The Score 1260 that offensive coordinator George McDonald will fill the position on an interim basis while the program searches for Moore’s replacement.

“George is probably the best college coach I have been around when it comes to coaching and developing wide receivers,” Shafer said.

Moore leaves a receivers group that struggled in 2013. After losing Adrian Flemming to a season-ending lower-body injury in its season opener, a depleted cast was unable to generate downfield threats. But with Jarrod West coming back for a fifth year, and a strong incoming quintet of pass catchers led by four-star signee K.J. Williams, the new group appears more fit for the open and dynamic offensive system SU is targeting next season.

Coach Moore is not only a great coach but an amazing person. Changing lives everywhere he goes, and now to the Buffalo Bills! Congrats Coach
