ESPN reported Moss, the assistant head coach to Mike McCarthy in Green Bay, met with friend and Raiders GM Reggie McKenzie.
According to the same report, the favorite for the job entering the week is Eagles offensive coordinator Marty Mornhinweg.
Mornhinweg remains a candidate for the opening in Indianapolis, where general manager Ryan Grigson has shown an interest in coaches with whom he has a working relationship. Grigson and Mornhinweg both arrived in Philadelphia in 2003 and had been with the Eagles until Grigson was hired as Colts GM two weeks ago.
"I feel as though I'm a tremendous competitor, so if a challenge was put before me that I felt as though I can excel at and would relish in taking on that opportunity, I would not be afraid of it," Moss told Packers beat reporters the day after the Giants game.
Report: Oregon's Kelly is Bucs' pick
Update: Here is a Monday morning update from this note from Sunday: Oregon coach Chip Kelly told the Tampa Bay Buccaneers that "his heart is with college football and Oregon," reported Tampa Tribune writer Rick Stroud.
Kelly met with the Bucs on Sunday night and canceled a recruiting trip to Sacramento, according to Stroud, so he could work out a deal. However, Kelly had a change of heart.
Here is Sunday's note:
The Tampa Bay Buccaneers are in negotiations to hire Oregon head coach Chip Kelly, according to KGW TV in Portland.
Kelly wasn't a known candidate for the position, but the TV station described the negotiations as "the final stages of the contract."
Kelly has been at Oregon for three seasons, leading the Ducks to three BCS bowls, including the 2012 Rose Bowl and the 2011 BCS National Championship. Oregon lost the 2011 championship on a last-second field goal to Auburn.
The Buccaneers fired Raheem Morris after the team went 4-12 in his second season and ended the year with 10 straight losses. Among those who have interviewed for the opening is Packers quarterbacks coach Tom Clements.
Kelly is an innovative offensive mind who ran a wide-open, shotgun spread system that incorporates multiple wide receivers but also utilizes personnel groups to run the ball effectively.
The Buccaneers are building around quarterback Josh Freeman, a franchise-type passer who regressed in 2011 because of injuries and an uneven running game. Freeman is a big, tall quarterback but his mobility, like that of Ben Roethlisberger, makes him difficult to bring down and he might thrive in an offense where he's surrounded by downfield threats.
Other known interviews in Tampa Bay include Mike Sherman, Brad Childress and Marty Schottenheimer, as well as Titans defensive coordinator Jerry Gray and Panthers offensive coordinator Jeff Chudzinski. Joe Philbin also interviewed for the job.
Progress made on HGH testing
The NFLPA has dropped its refusal of in-season HGH testing, which could be a breakthrough toward a resolution in the league's pursuit of an expanded and revolutionary drug-testing program.
CBS Sports reported the new proposal from the NFL Players Association was sent Friday and outlined the players' agreement to have in-season testing.
The sides agreed to collectively bargain the terms of HGH testing when the new CBA was ratified in August.
But to date, players have not approved the NFL proposals for testing and have questioned the process for gathering samples.
The World Anti-Doping Agency, which coordinates and promotes testing internationally, and an independent panel of physicians have written to the NFLPA to endorse the league's proposal.
