Walker wouldn't elaborate on whether there had been any change in his contract status. A team official who spoke to The Associated Press on condition of anonymity confirmed Walker had reported to camp Wednesday after flying to Green Bay from Phoenix.
Packers veterans are scheduled to report today and undergo physical exams Thursday. Full-squad practices begin on Friday.
Walker's agent, Drew Rosenhaus, said last week that his client would not report to the Packers' camp. Despite having two seasons left on his deal, Rosenhaus feels Walker deserves a new contract. Walker is scheduled to be paid $515,000 this season and $650,000 next season.
Walker skipped the team's off-season minicamps and off-season workout program. He has made more than $6 million in his first three seasons of the contract he signed as a rookie in 2002.
"I haven't had very many holdouts in my career, but I've been unable to get the Packers to commit to any discussion of a new deal," Rosenhaus said last week. "The Packers have refused to negotiate with us. They expect him to play the year out."
"I can't let this player go out on the field and jeopardize his career for that kind of money. I just can't fathom it," Rosenhaus said in an interview with HBO taped last Friday and scheduled to air this week.
Walker led the Packers in receiving last year when he caught 89 passes for 1,328 yards and 12 touchdowns.
Walker's holdout threat has drawn the ire of quarterback Brett Favre, who also criticized Rosenhaus for his tactics.
Nose tackle Grady Jackson, another Rosenhaus client, has threatened to hold out, but it is uncertain if he has reported to training camp today.
