EAST RUTHERFORD, N.J. -- Safety Kenny Phillips (knee) is doubtful for Sunday's showdown with the Dallas Cowboys, the New York Giants announced Friday. Receiver Mario Manningham (knee) is probable for the game.
The Giants will be relatively healthy in the Sunday night battle for first place, as running backs Ahmad Bradshaw (foot) and Brandon Jacobs (hamstring) and linebacker Michael Boley (hamstring) are all probable after a limited practice on Friday.
Phillips, who suffered a sprained MCL against Green Bay, did not practice all week but said Thursday that he planned to play against Dallas. Phillips rode the stationary bike and did some work with the training staff during the portion of practice open to the media on Friday.
With Phillips likely not playing, rookie Tyler Sash would step in at strong safety. Sash has played in every game this season, mostly on special teams. He played sparingly against Green Bay after Phillips exited with his injury.
"It's definitely exciting," Sash said the possibility of playing with the defense. "Everybody here wants to play, no matter what position they're at. It's definitely something I look forward to, depending on obviously the situations in the game and what personnel groupings we have in. I might get a chance, we'll see."
Manningham, who missed the last two games with his swollen knee, practiced in a limited capacity each day this week. The receiver said last week he had some "stuff" floating around in his knee and it prevented him from running at full speed. His return will make Sunday's game just the third time this season that Manningham, Victor Cruz, Hakeem Nicks and Ramses Barden are all active for a game.
"I feel like I'm 100 [percent]," Manningham said.
Baas did not practice this week. His intense headaches made him a late scratch for Sunday's game against Green Bay; the Giants have been testing him to find out more about the headaches that have been plaguin him.
"They are continuing to talk with the doctors and hopefully we'll have something shortly," Giants head coach Tom Coughlin said Friday.
Boley, Bradshaw and Jacobs all returned to practice on Friday in a limited capacity. Bradshaw's absence the previous two days was part of his routine of just practicing on Friday to keep him healthy as he returns from his fractured foot. He played for the first time in more than a month against Green Bay and gained 49 total yards.
Umenyiora is missing his second straight game with his injury, as is Herzlich. Paysinger will not play for the first time all season.
