The Dolphins are down to two quarterbacks on their active roster.
Miami announced Wednesday that they have waived rookie Brandon Doughty in order to open a roster spot for defensive tackle Chris Jones. The move comes a day after the Dolphins put defensive tackle Earl Mitchell on injured reserve.
Doughty was a seventh-round pick in April and completed 20-of-28 passes for 185 yards during the preseason. He was inactive for the opener as the No. 3 man on the depth chart behind Ryan Tannehill and Matt Moore. He could return to the practice squad if he clears waivers.
Jones was waived by Miami on September 3 as they set their initial 53-man roster. He originally joined the team off of waivers from the Patriots in April. He had 79 tackles and nine sacks in 28 games for the Patriots in 2013 and 2014, but spent last season on injured reserve.
