Although the cause of the debilitating neurological disorder is unknown, Gregg, 78, his family and his neurologist say his disease might be related to numerous concussions he suffered during his playing career in the 1950s at SMU and from 1956-71 with the Packers and Dallas Cowboys.
BENGALS: Rookie wide receiver A.J. Green said it’ll probably be a game-time decision whether he plays against the Ravens.
Green, a former Georgia Bulldogs standout, hyperextended his right knee while making a 36-yard touchdown catch Sunday against Pittsburgh and sat out the second half.
Green said he had an MRI that found a bruise.
Green leads NFL rookie receivers in catches (41), yards (635) and touchdowns (six). Four of his touchdowns have been on receptions of 35 yards or more, a sign of his ability to outrun defenders.
CHARGERS: Placed Pro Bowl left guard Kris Dielman on injured reserve due to the lingering effects of a concussion sustained Oct. 23 at the New York Jets.
He was originally slated to miss two games after the concussion and a grand mal seizure suffered on the plane ride home.
The team’s reaction to Dielman’s concussion came under scrutiny by the NFL and the NFL Players Association. He did not come out of the game even though he was visibly staggered by the injury, and wasn’t diagnosed until afterward.
EAGLES: Michael Vick did not practice Wednesday because of broken ribs, and it’s uncertain whether the Pro Bowl quarterback will play when Philadelphia visits the New York Giants on Sunday night.
Eagles coach Andy Reid says Vick is “still sore” and “these next few days will tell” if he plays Sunday.
JETS: Will be without running back LaDainian Tomlinson for tonight’s game in Denver against the Broncos, the team announced Wednesday afternoon.
Tomlinson currently is bothered by a sprained medial collateral ligament in his left knee. He suffered the injury on his final carry during the Jets’ 37-16 loss to the New England Patriots on Sunday night, and did not practice this week.
CHIEFS: Quarterback Matt Cassel had surgery on his injured throwing hand and coach Todd Haley still hopes that he will be back this season.
