The Minneapolis Star Tribune reported that Childress left town Wednesday night on a commercial flight and was scheduled to meet with Favre sometime Thursday at the player's home in Hattiesburg. Come Thursday morning, KMSP-TV in Minneapolis aired video showing a man appearing to be Childress entering Vikings headquarters.
A source close to the situation told ESPN's Rachel Nichols that Childress did not leave the Vikings' complex in suburban Minneapolis until early Wednesday evening and that Favre and Childress did not meet Wednesday night.
If Childress and Favre do talk, it is unclear where their meeting will take place, although it is believed they would meet face-to-face in Hattiesburg.
Childress will gauge Favre's level of interest in returning to the NFL to play for the Vikings. The future Hall of Famer quit football a second time after leading the New York Jets to a 9-7 record last season. Favre was hampered late in the year by a torn biceps in his throwing arm.
The biceps likely will be a topic of discussion between Childress and Favre. The Star Tribune reported that according to NFL sources, Favre would agree to undergo a minor procedure in which doctors would finish cutting the tendon. This procedure would have a quick recovery time, with Favre being ready to go before training camp.
Favre wanted to play for the Vikings last season, but the Green Bay Packers specifically eliminated their NFC North rivals as a destination when they negotiated the trade that sent Favre to the Jets last August.
Although Favre said he would not return next season, the Jets released him after drafting Mark Sanchez in the first round. Favre could see the Vikings as the opportunity to fulfill the goal he was deprived of last season -- winning a Super Bowl.
With Jackson battling injuries last season, journeyman Gus Frerotte started 11 games and led the Vikings in passing.
Minnesota finished 10-6 to capture the NFC North but lost to the Philadelphia Eagles in the first round of the playoffs in a game started by Jackson.
