Wide receiver Eddie Brown of the Cincinnati Bengals has a neck injury that could keep him sidelined for much of the 1992 season.
Brown, 29, suffered a ruptured cervical disk in the neck and will undergo surgery next week in Cincinnati. It is not known what caused the injury.
The Bengals are also concerned about the availability of linebacker Alfred Williams, No. 1 draft pick in 1991. Williams, 23, underwent a second surgery in an effort to correct a hereditary irregular heartbeat that has kept him out of workouts.
Quarterback Joe Montana of the San Francisco 49ers returned to the practice field but did not throw any passes and made only a few handoffs.
