Landry Jones replaces struggling Michael Vick at QB for Steelers

— -- PITTSBURGH -- Steelers quarterback Landry Jones replaced a struggling  Michael Vick and gave Pittsburgh's offense new life with two touchdown passes to Martavis Bryant Sunday against the Cardinals.

Vick was evaluated for a hamstring injury. He has not played well since taking over for an injured  Ben Roethlisberger in Week 3, throwing for less than 300 yards in his last 10 quarters of play, including a 3-of-8 performance for 6 yards in two-plus quarters Sunday against Arizona.

Jones' early-third-quarter score gave the Steelers a 12-10 lead. Jones threw the ball hard and high for a soaring Bryant, who barely kept his body in bounds.

Jones and Bryant hooked up for a touchdown again in the fourth quarter, an 88-yard scoring strike that gave Pittsburgh a 25-13 lead with two minutes remaining. It was the longest play from scrimmage in the NFL this season.

Jones briefly stepped in during the first half while Vick went to the sideline with dirt in his eye, but the second half marks the first extended NFL action from the fourth-round pick in 2013. Jones struggled for parts of training camp, so his presence on the field is hardly a sure thing.
