Baltimore quarterback Steve McNair passes against the New York Giants. The Giants won, 13-12, Sunday in Baltimore.

Baltimore ? A hard-hitting preseason game between the New York Giants and Baltimore Ravens produced far more injuries than touchdowns.

New York won, 13-12, Sunday night, but both teams lost key players during a physical affair.

Two members of the Giants’ starting defense left in the second quarter. Safety Will Demps, who started all 16 games last season, dislocated an elbow, and cornerback Sam Madison pulled a hamstring.

New York also lost two offensive players. Wide receiver Michael Jennings had three catches for 31 yards before rupturing his Achilles’ tendon, and Steve Smith, who caught a touchdown pass, left with a concussion.

Ravens cornerback Samari Rolle and receiver Mark Clayton sprained ankles.

In opening the preseason with a 29-3 rout of Philadelphia, Baltimore did not commit a turnover and was penalized only three times. Against the Giants, the Ravens had one turnover and received nine penalties in the first half alone.

“That was a disappointing first half,” Ravens coach Brian Billick said at halftime.
