PITTSBURGH -- Ben Roethlisberger has already proven he can win, leading the Pittsburgh Steelers to two Super Bowl victories.
Alex Smith, on the other hand, has never won a Super Bowl, but the Kansas City Chiefs believe he can return them to prominence after acquiring him from the San Francisco 49ers in an offseason trade.
Both quarterbacks threw their first touchdown passes and played well in their most extensive action of the preseason Saturday night as the Chiefs beat the Steelers 26-20 in overtime at Heinz Field as Rico Richardson caught a 15-yard touchdown pass from Chase Daniel with 8:53 left.
Roethlisberger completed 13 of 19 passes for 106 yards and one touchdown. Smith was 17 of 24 for 158 yards and one score. Both played the entire first half along with the rest of the first-team offenses.
Kansas City (1-2) forced overtime on Ryan Succop's 38-year field goal with 1:37 remaining in regulation. Pittsburgh (0-3) had gone ahead 20-17 on Shaun Suisham's 27-yard field goal with 11:10 left.
The Chiefs tied the game at 17-17 on the longest scoring play possible, a 109-yard kickoff return by rookie Knile Davis with 1:15 reaming in the third quarter. Davis, Kansas City's third-round draft pick from Arkansas, broke a tackle at the 15-yard line, cut to the right sideline at the 30 and outran everyone to the end zone.
Davis' score came right after the Steelers' third-round draft pick, wide receiver Markus Wheaton, caught a 34-yard touchdown pass from Bruce Gradkowski.
With Le'Veon Bell (foot) and Isaac Redman (stinger) sidelined, there was no clarity to who might open the season as Pittsburgh's starting running back.
Felix Jones, acquired on Thursday from the Philadelphia Eagles in a trade, had 29 yards on eight carries. Jonathan Dwyer ran for 25 yards in eight attempts and caught a touchdown pass.
Steelers' first-round draft pick, linebacker Jarvis Jones, suffered a chest injury in the third quarter while falling on a fumble and did not return.
The Chiefs' Jamaal Charles returned from a foot injury and was limited to just 10 yards on seven carries. He has just 23 yards in the preseason after rushing for 1,509 yards last season.
