Arthur has made 20 tackles in 14 games in 2011 as the primary backup to both Ngata and Cory Redding. He is "hungry" for a larger role, but he says he is content with being a backup for now. He left the Ravens' 20-13 win over the Texans with a leg injury, which head coach John Harbaugh has said is not serious.
Arthur made his first career start against the Cleveland Browns on Christmas Eve when Redding was scratched with an ankle injury. His parents, brothers and two-year-old son (Arthur IV) were at M&T Bank Stadium when he was announced as a starter and sprinted out of the tunnel and through a cloud of smoke onto the field. Chandler, who was witnessing an NFL game live for the first time, said the sight sent chills down his spine.
