PITTSBURGH - Neither the New York Giants nor the Pittsburgh Steelers know who will be their starting running back when the regular season begins.
Neither team found any clarity on Saturday night as the Giants defeated the Steelers 18-13 in a sluggish preseason opener for both teams at Heinz Field.
Andre Brown had 23 yards on four carries and David Wilson added 16 yards on five attempts for New York. They were listed as co-starters on the depth chart as the Giants look to replace Ahmad Bradshaw, who was released in the offseason.
Second-round draft pick Le'Veon Bell did not play for Pittsburgh, held out as a precaution because of a minor knee injury. Bell has been the talk of training camp as he had seemingly moved ahead of Isaac Redman and Jonathan Dwyer, though Redman was listed as No. 1 on the depth chart.
Dwyer had 15 yards on six carries and Redman ran twice for just 7 yards.
Meanwhile, fourth-stringer LaRod Stephens-Howling, signed as a free agent in the offseason from the Arizona Cardinals, ran for 40 yards on seven carries. He is considered more of a change-of-pace back who will likely make his biggest impact in the return game.
Both starting quarterbacks were pulled after the first quarter. New York's Eli Manning completed 2 of 5 passes for one touchdown - a 57-yard strike to Victor Cruz -- and Pittsburgh's Ben Roethlisberger was 4 of 8 for 36 yards.
Josh Brown kicked three field goals for the Giants as he takes over for Lawrence Tynes.
Steelers rookie quarterback Landry Jones had a forgettable first play that resulted in the Giants scoring a safety with 11:50 in the third quarter to increase their lead to 15-6. Jones collided with running back Baron Batch while attempting a handoff, fell on the ball in the end zone and was covered by safety Tyler Sash.
Pittsburgh scored its first touchdown as a direct result of a Giants mistake. A high snap sailed over quarterback Ryan Nassib's head and Adrian Robinson fell on it in the end zone.
