PITTSBURGH -- Third-stringer Joe Webb, the last healthy quarterback on the roster, led Carolina on the game's only touchdown drive as the Panthers blanked the Pittsburgh Steelers 10-0 on Thursday night in the preseason finale for both teams.

The Panthers (2-2) drove 90 yards in six plays for the lone touchdown, a 2-yard run by running back Fozzy Whitaker with 6:24 left in the third quarter, putting Carolina ahead 10-0. The score came one play after a 53-yard pass from Webb to wide receiver Philly Brown.

Webb threw for 116 yards, completing 8 of 11 passes, replacing Derek Anderson in the second quarter. Anderson left the game with a right hand injury after trying to recover a fumbled snap.

Starting quarterback Cam Newton did not play after sustaining a broken rib in the Panthers' previous preseason game against the New England Patriots.

Whitaker rushed for a game-high 91 yards on 23 carries. Wide receiver Kelvin Benjamin, the Panthers' first-round draft pick this year from Florida State, caught four passes for 56 yards.

Carolina's other points came on a 33-year field goal by kicker Graham Gano in the first quarter.

Landry Jones, in a bid to hang on to his job as the Steelers' third-string quarterback, played into the third quarter and completed 14 of 18 passes for 97 yards. The top two quarterbacks, Ben Roethlisberger and Bruce Gradkowski, did not play for Pittsburgh (1-3)

Rookie free agent quarterback Brendon Kay was 5-of-10 passing for 32 yards in his longshot attempt to make the team.

Steelers wideout Darrius Heyward-Bay led all receivers with six catches for 44 yards. Running back Josh Harris had 41 yards rushing in six attempts.

The Panthers could find themselves in a precarious situation after Anderson sustained a right hand injury in the second quarter. He was injured tackling Steelers right outside linebacker Jarvis Jones, who recovered a high snap while Carolina was in shotgun formation and was returning the fumble.

That left Webb as the Panthers' only healthy quarterback. He started three games in his first three seasons with the Vikings until Minnesota converted him into a wide receiver last year.

Webb signed as a free agent with the Panthers in the offseason when they offered him an opportunity to return to quarterback.

Gano accounted for all of the first-half points with a 33-yard field goal that capped a 14-play, 62-yard drive at the start of the game.
