CLEVELAND (AP) - Browns coach Mike Pettine is expected to hire Bills linebackers coach Jim O'Neil as his defensive coordinator and pluck other assistants from Buffalo's staff.
Bills coach Doug Marrone said Monday it was his understanding that O'Neil would be joining Pettine in Cleveland. O'Neil and Pettine spent one year together in Buffalo and four under Rex Ryan with the New York Jets.
Pettine is assembling his coaching staff after being hired last week as Cleveland's seventh coach since 1999.
Marrone also revealed Buffalo coaches Jeff Hafley and Brian Fleury are joining the Browns. Fleury, a quality control coach with the Bills, will be assistant linebackers coach with the Browns, Marrone said. Hafley is expected to coach Cleveland's secondary.
The Browns have provided no information on Pettine's staff or plans.
