Buffalo Bills running back Fred Jackson may have suffered a concussion in Sunday's game against the New England Patriots.

Coach Chan Gailey told reporters today that Jackson didn't feel well on the plane back to Buffalo due to concussion-like symptoms.

On the season, Jackson has 298 yards on 75 carries and three touchdowns. In yesterday's game in New England, Jackson had his best game of the year, recording 80 yards and scoring twice.
