Although James Harrison's devastating, illegal hit on Colt McCoy was witnessed by millions on television and thousands at Heinz Field, Cleveland's medical staff did not realize the severity of the blow when it treated the Browns' quarterback.
That was the explanation given by team President Mike Holmgren on Wednesday, one day after NFL medical officials and representatives of the Players Association met with the Browns to discuss the team's controversial handling of McCoy's head injury and possible changes to the league's policies on concussions.
Holmgren does not expect the league to penalize the Browns, who did not know McCoy had a concussion when they sent him back into last Thursday night's game.
Union chief DeMaurice Smith said the meetings allowed the NFLPA to learn more about McCoy's treatment.
"We will review the findings with our team and take into consideration the public comments made by the Browns," Smith said in a statement.
OWNERS APPROVE KHAN: Shahid Khan was 16 when he moved from Pakistan to the United States to attend the University of Illinois. While hanging out in the basement of his fraternity house, he began his American dream of owning an NFL team.
After building a multibillion-dollar company, Khan started working toward spending some of his fortune on fulfilling that college fantasy. He reached out to owners such as Wayne Weaver of the Jacksonville Jaguars to learn the business from the inside, and for them to get to know him.
Khan's dream-turned-plan crossed the goal line Wednesday. He joined the fraternity of NFL owners as his purchase of the Jaguars from Weaver was unanimously approved by the other owners.
The deal is for an estimated $760 million. The ownership transfer will be complete Jan. 4.
NFL RENEWS DEALS: The NFL has renewed its television deals with CBS, Fox and NBC for nine years through the 2022 season.
The current contracts expire after the 2013 season.
The league said Wednesday it would expand the number of Thursday night games on NFL Network but had not determined how many additional contests would be aired.
CBS, Fox and NBC will each televise three Super Bowls during the term of the contracts, continuing the current rotation.
Commissioner Roger Goodell says "the agreements would not have been possible without our new 10-year labor agreement."
The league had already extended its deal with ESPN for Monday night games.
PHILLIPS OUT WITH SURGERY: Wade Phillips, the veteran coach who has turned the Houston defense into the NFL's best, will have surgery this week to resolve a kidney condition and will be away from the team for a week to 10 days.
The Texans' defensive coordinator disclosed the medical issue Wednesday. He would not specify the condition, but said it is not life threatening, is not cancer, and that doctors recommended that he have the procedure.
