PITTSBURGH -- Ryan Nassib's preseason debut got off to a shaky start.

The rookie quarterback's first drive in the fourth quarter started with a 5-yard false-start penalty on Stephen Goodin. Nassib was sacked on the next play for a 3-yard loss. Two plays later, Nassib was flagged for delay of game on a third-and-17. Then, on the ensuing third-and-22 from the Giants' 16, a bad snap sailed past Nassib and Pittsburgh recovered for a touchdown to cut the Giants' lead to 15-13 with 12:04 remaining.

Nassib would take another sack on the next possession. But with 8:19 remaining, the fourth-round pick led the Giants on a 10-play, 54-yard drive that resulted in a field goal with 4:32 left. Nassib also completed a pass for 29 yards to Julian Talley on the drive.

"We'll have to let Ryan play some," said coach Tom Coughlin, who used Nassib behind Eli Manning, David Carr and Curtis Painter. "He was chased all over the place. He made the one play down the sidelines. We thought he might have gotten another one but he didn't have a whole lot of time. We need to work on that.

"He did make the play, though, that got the drive going to kick the field goal that kept it out of field goal range for [the Steelers]."

Injury report: Coughlin's mood after the Giants' preseason-opening win was subdued because of two injuries.

Kris Adams, a second-year wideout from UTEP, suffered a fractured lower leg in the third quarter. Adams was competing for a roster spot behind Hakeem Nicks, Victor Cruz, Rueben Randle, Louis Murphy and Jerrel Jernigan.

Also, backup guard Chris DeGeare suffered an MCL injury, according to the Giants, when a teammate unintentionally rolled up on DeGeare's right leg.

Brown fumble: Coughlin wasn't pleased to see Andre Brown fumble a pitch right early in the second quarter to give the Steelers the ball at the Giants' 44.

"His eyes never went to the ball," Coughlin said. "He was looking at the rush and fumbled. By the time he got to where he started looking for the ball, the defenders were on him. That was disappointing."

Brown and starter David Wilson combined for a total of 39 yards on nine carries. Seventh-round pick Michael Cox led the team in rushing with 33 yards.

"It wasn't much to talk about," Coughlin said of the running game. "I don't know how many chances we had. It wasn't anything great. We played that first offensive line a few more plays than we intended. We'll have to improve in that area. No question."
