‘Buffalo will this week seek further development from second-year quarterback J.P. Losman, who completed 7-of-14 passes for 59 yards, rushed five times for 36 yards, and bolted for a one-yard touchdown in last week’s win against Green Bay. Losman has been handed the starting signal-caller job but has just five career regular season pass attempts. Former Brown Kelly Holcomb (10-14 passing, 94 yards in the preseason) has looked sharp thus far in August. Running back Willis McGahee garnered his most extensive work of the preseason last week, when he rushed nine times for 32 yards and scored on a six-yard rush against Green Bay. McGahee and the Bills starters will probably play all or most of the first half on Friday. Tight end Tim Euhus (strained pectoral muscle) and wideout Roscoe Parrish (wrist) are among the Bills who will not be in uniform on Friday.’
