Four NFC North players reported Tuesday

Tuesday came and went without much clarity on when this period of lockout purgatory will continue in the NFL. But for those interested, let's wrap up what happened in the NFC North:

Chicago Bears: Three players showed up at Halas Hall, according to team president Ted Phillips. Place-kicker Robbie Gould, defensive end Israel Idonije and defensive tackle Matt Toeaina were allowed into the building but were restricted from using the facilities. "... [W]e're not opening the building for business yet,' Phillips said. "Hopefully we will soon."

Detroit Lions: According to multiple reports, no Lions players showed up at the team's Allen Park practice facility. Defensive end Kyle Vanden Bosch, the team's player representative, advised players against it. Vanden Bosch, via Tom Kowalski of Mlive.com: ""My understanding is that the doors to the facility would be open but we wouldn't be able to work out or talk to our coaches much. I don't know how much progress would be made or what the benefit might be. We'll wait until things become clearer."

Green Bay Packers: According to team president/CEO Mark Murphy, no players showed up at Lambeau Field. Murphy, who has a key NFL role as a member of the Management Council Executive Committee, said he anticipates more clarity by the end of this week. Rob Demovsky of the Green Bay Press-Gazette has more.

Minnesota Vikings: Backup linebacker Erin Henderson was the only player to visit the Vikings' Winter Park facility. He departed after being told he could not use the cold tub. Coach Leslie Frazier said he had a "very brief conversation" with Henderson as he moved through the building.

According to NFL.com, the NFL Players Association has recommended that agents immediately begin initiating contract discussions with teams. But it's safe to say that teams aren't going to respond. Vikings vice president of player personnel Rick Spielman said teams were instructed to maintain the lockout "status quo" -- when contact with veteran players and agents was barred -- until further notice.
