OTA practices are voluntary and players are not required to attend.
Linebacker NaVorro Bowman was also not present though he was given the day off by 49ers coach Jim Tomsula. Bowman missed the 2014 season after sustaining an ACL tear during the 2013 playoffs.
Tanner has been with the Saints since 2010 but has never appeared in a game.
According to the Charlotte Observer, wide receiver Kelvin Benjamin strained his hamstring a week ago and will probably sit during next week's practices as a result. Benjamin, a rookie in 2014, had 1,008 yards and nine touchdowns for the Panthers.
With Benjamin sidelined, rookie receiver Devin Funchess has a chance to step in and act as Carolina's No. 1 receiver during the upcoming voluntary practices.
The wide receiver and running back performed so well in OTA work Wednesday that Pagano claimed that it appeared they had been with the organization for years.
"Pretty seamless," Pagano said about their work. "They don't miss a beat as far as the playbook goes, knowing what to do. Every time I see them in the huddle, break a huddle, to me it looks like they're going the right direction. They're lining up right. They're very talented, talented guys. They fit right into the locker room. They're professionals. ... They're not talkers. They're workers, they're doers."
Both veterans, however, have shown signs that their best days are behind them. The 33-year-old Johnson failed to reach 1,000 yards receiving last season for Houston for the first time in his last seven full seasons. The 32-year-old Gore managed another 1,000-yard performance in 2014, but his total was its lowest of any in a full season since 2008.
Tanner, who has never played in a regular season game with the Saints, has been with the franchise since 2010 as a member of the practice squad.
McGlynn was a fourth-round pick by the Eagles in 2008. He is coming off a forgettable season where he allowed the most sacks of anyone on the offensive line as a member of the Chiefs.
Wednesday marked the second day of the Jets' 10-day voluntary workout program. Marshall was present on the first day but Richardson was not.
Jets coach Todd Bowles said Marshall was absent on Wednesday because he "had something to take care of, but "it wasn't conveyed" to him why Richardson was not there.
Richardson was the NFL's Defensive Rookie of the Year in 2013 and is projected to play a key role on the Jets' defense.
Montgomery has been described by the team as Randall Cobb-type player, so expect the Pack to use him as a return specialist early on.
Wilkerson's absence is no surprise, as the defensive lineman is seeking a new contract from the team and has stated he won't take part in voluntary team activities. Richardson and Marshall are not involved in contract disputes.
Washington has yet to appear in an NFL game.
Gardner, who will play wide receiver in the pros, was waived by New England on Monday after signing as an undrafted free agent. Gardner threw for 2,960 yards in his junior year at Michigan with 21 touchdowns and 11 interceptions.
