MIAMI -- The Dolphins promoted John Benton to offensive line coach, the team announced Saturday.
The Dolphins first hired Benton, who formerly worked for the Houston Texans, on Jan. 29 as an assistant offensive line coach.
The Dolphins also announced Jack Bicknell Jr. will fill Benton's former role. Bicknell previously worked with the Pittsburgh Steelers.
"With the promotion of John Benton, along with the addition of Jack Bicknell Jr., we have two experienced football coaches who have an impressive history working with and developing quality offensive line units," Dolphins coach Joe Philbin in a statement. "They are both excellent teachers and are highly respected within the coaching community. Both coaches will be great assets to the Miami Dolphins organization."
Miami's offensive line was arguably the weakest part of the team last season. The Dolphins allowed a franchise-record 58 quarterback sacks and finished 26th in rushing.
The Dolphins' poor offensive-line culture also was exposed in Ted Wells' investigation into the team's bullying scandal. Two of those players cited in Wells' report -- Incognito and starting guard John Jerry -- are unrestricted free agents and are not expected to return.
