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. We made mistakes and committed penalties after not doing either of those last week," Ravens coach Brian Billick said at halftime. "I thought we'd have better focus, I really did."The game was as sloppy as it was physical. New York (1-1) was penalized 11 times for 106 yards, and Baltimore (1-1) was called for 11 penalties totaling 66 yards.Ravens quarterback Steve McNair played three series, going 5-for-8 for 29 yards with one interception. Running back Willis McGahee played much of the first half, gaining 3 yards on six carries and catching one pass for a yard.Giants quarterback Eli Manning played deep into the second quarter, going 10-for-13 for 114 yards and producing the game's lone touchdown.Vying to replace the retired Tiki Barber as New York's starting running back, Brandon Jacobs and Reuben Droughns each received six carries during the first half. Jacobs rushed for 23 yards and Droughns gained 11.The Ravens took advantage of a turnover by Manning to go up 3-0 in the first quarter. After a sneak by McNair came up short on fourth-and-1 from the New York 20, Manning fumbled without being hit and Baltimore recovered on the 12. Matt Stover then kicked a 33-yard field goal.Manning made amends by capping an 80-yard drive with a 10-yard touchdown pass to Smith. Jacobs accounted for 25 yards rushing on four carries.Stover kicked a 47-yard field goal late in the half to make it 7-6.After a scoreless third quarter, New York's Josh Huston kicked field goals of 50 and 30 yards around a 40-yarder by Baltimore's Rhys Lloyd, who added a 38-yarder with 2:39 left.Against the Eagles, Baltimore drove 93 yards for a touchdown on its opening possession. This time, playing in the rain, the Ravens sputtered at the outset.Top draft pick Ben Grubbs, starting for injured Chris Chester at right guard, jumped offside before the first snap. McGahee followed by losing 5 yards on a run, and Baltimore punted.Things worsened for the Ravens on New York's initial play from scrimmage. During a 17-yard completion from Manning to Jennings, Rolle twisted his right ankle and had to be helped from the field.The Ravens' next drive ended with an interception by Madison after McNair threw deep into double coverage."It just wasn't there tonight," McNair said. "It started off wrong with penalties and I had a turnover. It's something that's better to happen now than later."
