Culpepper started six games for the Raiders last season. Since he sustained a severe knee injury in 2005, it has been difficult for him to regain the Pro Bowl form of his Minnesota glory days when he was throwing long touchdowns to Randy Moss.
Culpepper, 31, arrived in Green Bay on Tuesday evening and spent most of today at the team's facility, according to the Green Bay Press-Gazette.
"We had him in for a visit, and it was a good visit," General Manager Ted Thompson told the Press-Gazette. "We wanted to kind of introduce ourselves to him and he to us, so it went fine."
Culpepper, an unrestricted free agent, signed a one-year contract with the Raiders last summer before a hamstring injury ended his season.
Culpepper completed 58.1 percent of his passes for 1,331 yards with five touchdowns and five interceptions last year. He spent the previous season with the Miami Dolphins.
