PITTSBURGH (AP) Pittsburgh Steelers wide receiver Martavis Bryant made his 2015 debut a memorable one.

Bryant caught six passes for 137 yards and two second-half scores in Sunday's 25-13 win over Arizona in his first action of the season. Bryant sat out the first four games for violating the league's substance abuse policy and missed another one with a minor knee injury.

Bryant says he wants to prove to the Steelers he's more than a one-dimensional threat. He thrived while working with third-string quarterback Landry Jones, who could start again in place of Ben Roethlisberger on Sunday when Pittsburgh plays at Kansas City.

Roethlisberger will practice this week, but his status remains uncertain as he continues to rehab his sprained left knee.
