Newcastle United have signed left-back Paul Dummett to a long-term contract extension which could run until 2022. The 26-year-old has been a fixture in Rafael Benitez's side since returning to action in December from a hamstring injury suffered during the opening game of the season. Newcastle have won three and drawn four of their last nine games, while conceding only eight times, since Dummett returned and Benitez sees him as an essential member of his squad.
