The people said the Indianapolis Colts quarterback was seen recently in Los Angeles by Dr. Robert Watkins, who determined the stability in Manning's neck would have allowed the NFL's only four-time most valuable player to play if he had a game this Sunday.
But arm strength is apparently the issue because his ability to play depends on the nerves in Manning's arm regenerating to a satisfactory performance level.
Watkins also reportedly told Manning to continue an aggressive rehabilitation path toward playing in 2012.
The Green Bay Packers chose Tom Clements as their new offensive coordinator.
Clements has been the Packers' quarterbacks coach since 2006.
Mickelson sues over postings
Golfer Phil Mickelson filed a lawsuit against an Internet service provider in Canada to learn the identity of a person who has been posting "vexatious statements" that the four-time major champion says are a deliberate attack on his reputation.
"I'm all for freedom of speech, but I won't tolerate defamation," Mickelson said Thursday after his opening round in the Phoenix Open.
In his lawsuit against Videotron S.E.N.C. in Quebec Superior Court, Mickelson cited comments posted on Yahoo Sports on Nov. 11 and 12, in which one or more persons under the pseudonyms "Fogroller" and "Longtitude" made statements that alleged, among other things, that Mickelson's wife had an affair and that he fathered an illegitimate child.
Gonzalo Fernandez-Castano birdied his last three holes for a six-under-par 66 in the Qatar Masters at Doha, overcoming wind and blowing sand to lead John Daly by a shot after the first round.
The game will be played at Kino Veterans Memorial Stadium, with all proceeds going to the foundation named for the daughter of Dodgers scout John Green. Christina-Taylor Green was among six people killed in the January 2011 shootings in Tucson that also wounded retired U.S. Rep. Gabrielle Giffords. The youngster was the granddaughter of former major league manager Dallas Green.
According to people familiar with the episode, Hamilton drank alcohol on Monday night at a bar in Dallas. This was Hamilton's second alcohol-related relapse in three years. In January 2009, he drank to excess at a bar in Tempe, Ariz.

Right-hander Micah Owings and the San Diego Padres agreed to a $1-million, one-year contract.
