Jackson has missed time with a groin injury in practice this week, after not being able to finish last week’s win over the Redskins.
“I’m not 100 percent, but I’m day-to-day,” Jackson said Thursday. “The injury is not as significant as we once thought it was, and we’re just going to go from there. I still have another three days before the game. So each and every day buys me time.
New left tackle Wayne Hunter (subbing for the injured Radger Saffold) practiced Friday and is expected to play.
Rookie defensive tackle Michael Brockers (ankle) was out of his walking boot and working on the side, a positive sign for the first-rounder.
