EAST RUTHERFORD, N.J. -- Cornerback Prince Amukamara did not practice due to a hamstring injury, described by Tom Coughlin as "tricky."

Safety Kenny Phillips (knee), linebacker Michael Boley (shoulder), wide receiver Hakeem Nicks (knee), Jason Pierre-Paul (back), safety Tyler Sash (hamstring) all appeared to not be practicing during the early portion of practice open to the media.

Running back Ahmad Bradshaw was not on the field, perhaps getting treatment for his sprained knee which threatens his availability for Sunday's game.

Here's the pre-practice injury report. We'll have the official injury report up when it is released later today:

CB Prince Amukamara (hamstring)
C David Baas (shoulder)
TE Travis Beckum (knee)
RB Ahmad Bradshaw (knee/foot)
WR Hakeem Nicks (knee)
DE Jason Pierre-Paul (back)
S Kenny Phillips (knee)
S Tyler Sash (hamstring)
