Troy Aikman had a stiff neck and headache Monday but vowed he'll start against the San Francisco 49ers.
Aikman suffered the fifth concussion of his NFL career in the first period of the Dallas Cowboys' 13-12 loss to Philadelphia.
"I have no doubt I'll be fine," Aikman said. "I felt I could have played in the second half yesterday. I felt I had gained my senses and could go back in but the doctors wouldn't let me."
Green won't be fired
EDEN PRAIRIE, Minn. -- While NFL commissioner Paul Tagliabue intervened Monday in Dennis Green's feud with the Minnesota Vikings, Green's boss said there won't be a coaching change during the season.
Vikings president Roger Headrick said he could envision no scenario under which Green would be fired this season, despite Green's bizarre threat to sue for control of the team.
Green stunned the organization and the league late last week with the release of his autobiography, "No Room for Crybabies." In it he presented a detailed plan in which he could either buy majority control in the Vikings or sue two owners to reach that end.
Green backpedalled after Sunday's victory at Tampa Bay, saying he was only "thinking out loud" when he wrote the final chapter of his book. He denied his plan should be considered a threat to the owners.
Green spoke with Tagliabue on Monday for the first time since the dispute became public. Headrick said he believed the commissioner planned to ask Green to make a statement, either publicly or in private to the owners, that would diffuse the controversy.

Jaguars quarterback Mark Brunell can't put his broken finger on the football. Brunell dislocated the middle finger of his throwing hand three plays from the end of regulation in Pittsburgh's 23-17 overtime victory. He wore a splint on Monday, and coach Tom Coughlin said the Jaguars might not know until later this week whether he'll be able to play Sunday against Tennessee.
The NFL is looking into what Jacksonville receiver Keenan McCardell says was behind a crushing hit he took from Pittsburgh linebacker Greg Lloyd. McCardell said Lloyd, who knocked the wind out of him with a hit away from the ball on the first play from scrimmage, accused him of making a threatening phone call to Lloyd's family. McCardell, a Pro Bowl receiver, denied making the phone call. He suggested someone on the Steelers' staff made the call to motivate Lloyd.
The Falcons waived quarterback Billy Joe Tolliver and signed Jim Miller. Receiver Freddie Scott also was waived so the Falcons (1-7) could sign Mercury Hayes.
Cincinnati defensive back Tremain Mack, sidelined the past month with a severely sprained foot, will be out another month while he serves a 30-day DUI sentence in jail.
