Jackson uncertain after concussion
Meanwhile, running back Brian Westbrook will be re-examined this week after missing the last two games with his second concussion of the season.
Jackson was injured on a hit after running a short crossing pattern in the third quarter. He didn't lose consciousness and left the field on his own.
"He doesn't feel bad today," coach Andy Reid said Monday. "We are as cautious as they come with concussions. We're going to continue to test him and go through the process."
The diminutive Jackson -- he's generously listed at 5-foot-10, 175 pounds -- is susceptible in traffic because of his size. He leads the team with eight touchdowns, all of which are 35 yards or more.
"We'll just see how he does over the next few days," Reid said. "That hit was more of the shoulder. It really wasn't on the head."
The team expects Westbrook to see specialists this week in Pittsburgh. The doctors said they wanted to see Westbrook 2-3 weeks after their previous exam Nov. 18.
"I'm not sure exactly what step the doctor will take with him," Reid said. "I don't know that. We'll see what phase the doctor feels he's at and the doctor will determine what he will do. If that's going back on the field, we'll do that. If that's more conditioning work in the weight room, we'll do that."
Westbrook experienced a mild headache last week after a workout. The 30-year-old former All-Pro sustained his first career concussion when he hit his head on a defender's knee during a Monday night win at Washington on Oct. 26. He briefly lost consciousness but walked off the field under his own power.
Westbrook returned against San Diego on Nov. 15 after missing two games. But he sustained another concussion when he got sandwiched between a blocker and a tackler on a screen play.
"I know a lot is being said about concussions," Reid said. "We are as conscious as they come with concussions. We are going to do everything within our power to get [Jackson] the proper treatment and diagnosis. To compare to Brian's, are we going to be more cautious? No. We're always cautious. We're going to do what we do."
