With their struggles along the interior of their defensive line still an issue, the Washington Redskins are hosting free agent defensive tackles Terrance Knighton and Phil Taylor for visits on Monday, according to people familiar with the situation. Team officials planned to work both players out and could wind up signing at least one. Knighton spent the 2015 season with Washington, but the team let him depart via free agency although the player — a fan favorite, nicknamed “Pot Roast” — wanted to remain with the team. Knighton struggled to keep his weight under control and played at around 400 pounds last season. He signed with the New England Patriots, but didn’t survive roster cuts following the preseason. Redskins players have lobbied for the re-signing of Knighton. But team officials hadn’t made the move. However, with Washington ranked last in the NFL, giving up an average of 5.1 yards per rushing attempt, team officials are considering bringing Knighton back. Two people familiar with the situation said that Knighton has lost weight and now weighs around 365, which could help his stamina and effectiveness.Taylor didn’t play last season after suffering a knee injury in training camp of 2015 with the Denver Broncos. The 6-foot-3, 335-pound Taylor was a first-round pick of the Cleveland Browns out of Baylor in 2011. (He initially played for Penn State with Redskins defensive end Chris Baker, but both got dismissed from the program). Taylor spent four seasons with Cleveland before signing with Denver in the offseason of 2015. For his career, he has 109 tackles and seven sacks. The Redskins on Sunday gave up 128 yards to the Baltimore Ravens and haven’t held a team under 100 yards in five games this season.
