Lorenzen hands off

Eli Manning threw the only touchdown of the game as the Giants squeaked by the Baltimore Ravens, 13-12,  in preseason action.  Manning played almost the entire first half and went 10-for-13 with 114 yards and a score.  Steve Smith caught the touchdown but left the game after suffering a concussion on the play for the Giants, who bounced back  from a 24-21 loss against the Panthers in their preseason opener.  Two members of the Giants’ starting defense left in the second quarter as safety Will Demps, who started all 16 games last season, dislocated an elbow and cornerback Sam  Madison pulled a hamstring.  New York also lost wide receiver Michael Jennings, who had three catches for 31 yards before rupturing his Achilles’ tendon.
