Murphy is coming off a season that saw him play in all 16 games.
Murphy fell and twisted his left knee awkwardly in the first quarter of the team's preseason game against the Ravens Thursday night. Coaches have been pleased with how he's performed in practice.

Murphy was already suspended for the first four weeks of the regular season for violating the league's policy on banned substances.
