A Pro Bowler last season, Tuck injured his left shoulder following a cheap shot tripping penalty on Cowboys OT Flozell Adams. Hixon sprained his knee in the early going against Dallas and was forced from the contest.
"They are going through all the tests and we will have to wait and see what the tests say to see where these guys are," Coughlin said. "I think a big factor will be Wednesday. When we do get the information, how do they feel on Wednesday?"
Mathias Kiwanuka filled in admirably for Tuck and Mario Manningham certainly stepped in just fine for Hixon. But Coughlin clearly wants one of his top defenders and one of his starting receivers back in action as soon as possible.
There was also no news on the trio of injured defenders that missed last Sunday night's game in Dallas – CB Aaron Ross, CB Kevin Dockery and DT Chris Canty.
"The early prognosis is not that different from what we finished last week with," Coughlin said. "And so again, we'll see. I think it ends up being, hopefully, a day-to-day thing. But we will have to find out."
However, Coughlin was pleased with one piece of injury business – the return to action of LB Michael Boley, who posted seven tackles for New York in his Giants debut.
"It was good for him to be in there – I thought he did well," Coughlin said. "There are things that he is going to have to improve on. But to get out there and get in the game, to play as much as he did, was a positive thing."
