Percy Harvin was the first player to arrive at Winter Park as the team reopened for business on Tuesday morning.
So far about 15 players have been seen entering the facility -- or tweeted they were in the facility by 10:45.
Harvin and cornerback Cedric Griffin, coming off a knee injury, already have come and gone.
Quarterback Christian Ponder tweeted that he was on his way to Winter Park. Although Ponder has yet to sign, he is allowed to voluntarily show up.
Other players at Winter Park were Rhett Bomar, Everson Griffen, John Sullivan, Jaymar Johnson, Jim Kleinsasser, Toby Gerhart, Kyle Rudolph, E.J. Henderson, Chris DeGeare and Brian Robison.
The Vikings, meanwhile, are busy working the phones at Winter Park as teams are allowed to begin speaking to, but not signing, veteran free agents today.
They have also signed undrafted free agents today but likely won't release that list until all those signings are complete. They could also attempt to sign Ponder and other draft picks today.
There already have been several reports, tweets and even Facebook messages about undrafted rookies who have agreed to terms with the Vikings. This (unofficial) list includes wide receivers Andre Holmes of Hillsdale College and Dominique Johnson of Cal Poly; running backs Matt Asiata of Utah and Derrick Locke of Kentucky; tight end Allen Reisner of Iowa; kicker Nate Whitaker of Stanford; guard Conan Amituanai of Arizona; linebacker Larry Dean of Valdosta State; and defensive back Devon Torrence of Ohio State.
