The Green Bay Press-Gazette, citing two sources -- one in the NFL, another close to Favre -- reported that Favre does not have a team-issued cell phone.
"One-hundred percent, without a doubt, no Packers-issued phone," the source close to Favre said, according to the report.
On Tuesday, the Milwaukee Journal Sentinel reported that Favre, who announced he was retiring in March but since has expressed his desire to return to the NFL, had used the team-issued phone to contact Childress and Bevell, the Packers' former quarterback coach.
That report followed the Packers filing a tampering charge against the Vikings, claiming that their NFC North rivals had improper conversations with Favre about coming out of retirement and playing for them.
While the NFL is probing those allegations, the two sources said Favre doesn't have a phone paid for by the team, the Press-Gazette reported.
According to the report, the sources said there are no indications the Packers have given team-issued phones to any of their players -- and that doing so would violate NFL salary-cap rules unless the Packers included the cost of the phones on their salary cap.
The Minneapolis Star Tribune reported Wednesday that NFL security staff paid a visit to the Vikings facility in Winter Park, Minn., on Tuesday to investigate the tampering claims. The Vikings could face fines and/or forfeit draft picks if they are found to have tampered with Favre, who is still under contract with the Packers.
