‘Losman completed all five of his pass attempts and McGahee scored on a 1-yard run, helping the Buffalo Bills beat the Detroit Lions 20-13 Thursday night in the exhibition finale for both teams. Losman threw for 52 yards, and McGahee ran for 29 yards and the TD on the opening 13-play, 85-yard scoring drive. Losman, who won the starting job earlier this week, also played in Buffalo’s second series but didn’t attempt a pass.’
