"He is day-to-day," coach Tom Coughlin said.
Toomer was hurt late in the fourth quarter of last week's 28-13 loss to Detroit in Giants Stadium.
"Right at the end of the game, he just felt like he was starting to strain, so we took him out right at the end there in that last two-minute drive and felt like we got him before there was anything seriously done," Coughlin said. "It stayed in the strained category. It's just one of those things. He's got real good strength, he's just sore and we just have to continue to work that out.
"We were encouraged by the immediate response of the medical people. We felt like he may very well have been in good shape by mid-week, but it wasn't to be that way, so now it'll end up being day-to-day. He's trying to stay as upbeat as he can and we work him on the side and straight ahead he is not too bad, so he's made good progress."
Toomer, who has caught a pass in a Giants-record 89 consecutive games, did not speak to the media today. If Toomer cannot play, rookie Jamaar Taylor, who made his NFL debut with two receptions in last week's loss to Detroit, will likely start in his place.
*Center Shaun O'Hara did not practice.
"He has an infection (in his leg) and we're going to try to figure out what that's all about," Coughlin said. â€œHopefully, it'll be controlled and he has to see the medical people about that."
* Defensive end Michael Strahan was excused from practice today to be with his wife Jean, who was scheduled to give birth to twin girls.
