Head coach Andy Reid said on Monday that fullback Leonard Weaver and center Jamaal Jackson will each undergo surgery for injuries that were incurred during Sunday's loss to the Green Bay Packers.

Weaver suffered what was described by Reid as a "very severe ACL tear" in his left knee. Weaver was injured on a run up the middle for no gain in the second quarter. As Weaver fought for yards, his leg got caught in the pile, was pushed back and hyperextended. No date has been set for Weaver's surgery.

Jackson was injured on a run by Mike Bell up the middle later in the second quarter. Jackson ran over to the sideline to call for Mike McGlynn to take his place. Jackson will undergo surgery on Tuesday.

Eldra Buckley replaced Weaver at fullback. Reid said that Jason Davis, a former Eagle, and Owen Schmitt are visiting the Eagles as potential replacements for Weaver. Reid did acknowledge that Weaver would have been on the field for the fourth-and-1 late in the fourth quarter that the Eagles were unable to convert which then allowed the Packers to run out the clock.

Reid said that he and general manager Howie Roseman are exploring the team's options for offensive linemen, although Reid said that McGlynn was "one of the guys who came in and did a nice job."

Last week, the Eagles had a clean injury report but that will not be the case this week. In addition to the injuries suffered by Weaver and Jackson, quarterback Kevin Kolb and linebacker Stewart Bradley each suffered a concussion. Neither player has been ruled out for this Sunday's game in Detroit, but Reid said that each player must first pass a series of tests before being able to return.

Reid also said that defensive end Antwan Barnes suffered a wrist sprain, running back Mike Bell has a toe strain, defensive tackle Brodrick Bunkley has an ankle injury as does guard Todd Herremans, defensive tackle Trevor Laws incurred an oblique strain and offensive tackle Jason Peters has a knee sprain. All of those injuries are considered day-to-day.
