(AP) Big Ben's big night gave the Pittsburgh Steelers a big boost in the AFC North.

Ben Roethlisberger threw for 309 yards and three touchdowns, helping the Steelers overcome their offensive woes and leading them to a 26-21 victory over the Jacksonville Jaguars on Sunday night.

Pittsburgh (4-1) snapped a four-game losing streak against Jacksonville and stretched its division lead over Baltimore (2-2), which lost to Tennessee earlier in the day.

Roethlisberger finished 26-of-41, rebounding from an interception on his third pass that Rashean Mathis returned 72 yards for a score. Roethlisberger's perfect 8-yard fade pass to Hines Ward in the corner of the end zone put the Steelers ahead 26-21 with 1:53 remaining.

Roethlisberger misfired on the 2-point conversion, but Pittsburgh's defense sealed the win by sacking David Garrard and then forcing two incomplete passes.
