Eagles coach Andy Reid said Brian Westbrook was undergoing testing in Pittsburgh for his concussions "as we speak" during his morning news conference. "We'll know more on him the next day or two," Reid said.
Reid said Westbrook "didn't seem rattled" when Reid spoke with him Monday. "He was in a good place."
In case there was any doubt, Westbrook will not play Sunday against Chicago.
Westbrook suffered his second concussion in three weeks when he was sandwiched on a screen pass against San Diego. He previously was concussed against Washington and then missed the next two games.
Reid mentioned fullback Leonard Weaver as part of the reason why he didn't feel he needed to make a roster move. The Eagles have rookie LeSean McCoy, Eldra Buckley and recently signed P.J. Hill behind Westbrook, although Hill has not been active since signing with the team.
Reid said McCoy has played better when he got more of the reps during the week in practice. That is the case this week.
Eagles quarterback Donovan McNabb said several players who are playing despite repeated concussions. "It's a scary decision you have to make; that's why you go see the specialist," he said.
"I look for him to be back," McNabb said, though "whatever decision Brian makes will be the best decision for him.
"It's out of Brian's hands, it's in God's hands."
In other injury news, Macho Harris is out today with an eye infection, although that is deemed to be not a big deal.
Sheldon Brown is "doing better" with his hamstring injury, Reid said, but he won't practice.
Akeem Jordan (hyperextended knee) and Quintin Demps (high ankle sprain) also will not practice. Kevin Curtis, recovering from knee surgery, is out against Chicago.
Jason Peters will practice today after sitting out against the Chargers with an ankle injury.
