New York Giants quarterback Eli Manning took some snaps, made a few handoffs and tossed lightly to test his bruised right shoulder Wednesday.
He did not participate in practice and coach Tom Coughlin gave no indication whether Manning would play Sunday against Green Bay.
Backup QB Jared Lorenzen took snaps with the first team, and will make his first career start Sunday if Manning can't play.
Manning has started the last 42 regular season and playoff games for New York. He completed 28 of 41 passes for 312 yards and four touchdowns before he was forced to leave Sunday's loss at Dallas in the fourth quarter.
