PITTSBURGH -- Dominated for a half, the Steelers rallied for a 25-13 over the Arizona Cardinals yesterday led by two players who have spent portions of their young careers either buried in the doghouse or depth chart.

Landry Jones threw a pair of touchdown passes to Martavis Bryant after relieving Michael Vick, the second a spectacular 88-yard catch-and-run that sealed it with 1:58 to play.

Bryant, active for the first time this season after being suspended four games for violating the league's substance abuse policy and missing another with a knee injury, somersaulted across the goal line in joy while Jones was thrust into the air by guard David DeCastro.

"I just can't believe I got in the game," Jones said. "I'm still kind of reeling from it."

So are the Cardinals (4-2), who overwhelmed the Steelers (4-2) in the first half but only had a seven-point lead to show for it. Once Jones replaced Vick, who completed just 3 of 8 passes for 6 yards before exiting in the third quarter with a right hamstring injury, Pittsburgh's offense looked like the one Ben Roethlisberger guided before spraining his left knee in Week 3.

Jones found Bryant for an 8-yard TD that put the Steelers in front, the second of five straight possessions in which Pittsburgh scored.

"Landry was like Ben's little brother out there," Steelers running back Le'Veon Bell said. "He was out there making checks and everything and it brought us back, like 'Dang, Landry really got this. After he scored the first touchdown, it was like a confidence booster."

Jones finished 8-for-12 for 168 yards and the two scores. Bryant caught six passes for 137 yards, Bell ran for 88 yards and rookie Chris Boswell kicked four field goals as Pittsburgh steadied itself the moment Jones entered the huddle.

"He played very well for a young guy to come in in that situation," Arizona coach Bruce Arians said. "He won the football game."

Cardinals QB Carson Palmer threw for 421 yards with a touchdown and two interceptions. John Brown caught 10 balls for 196 yards, but Arizona collapsed in the second half to ruin Arians' homecoming. The longtime Pittsburgh offensive coordinator was pushed out after the 2011 season, something he jokingly called a "refirement."
