The Giants traded star defensive tackle Damon “Snacks” Harrison to the Lions for a draft pick.

Giants coach Pat Shurmur confirmed the deal Wednesday after practice without revealing any details. The teams are expected to confirm the move Thursday after Harrison passes a physical.

A person with knowledge of the deal told The Associated Press that Giants will receive a fifth-round draft pick for the soon-to-be 30-year-old Harrison, who was a 2016 All-Pro selection.

The trade is the second for the Giants (1-6) in less than 24 hours and indicates the organization is cleaning house. The Giants sent cornerback Eli Apple, a 2016 first-round selection, to the Saints for two picks on Tuesday.

Reid grievance denied: Eric Reid’s grievance against the Bengals was denied by an arbitrator, a decision that irked the NFL Players Association.

The union said arbitrator Shyam Das found that the team asking Reid during a free-agent visit if he planned to kneel during the national anthem violated fair hiring practices. The grievance claimed that Reid wasn’t signed by any team because of his protests.

Reid is now with the Panthers, whom he joined this month and with whom he has continued to kneel.

Griffen returns: Everson Griffen was back at practice with the Vikings for the first time in almost six weeks. The first and most important step was acknowledging his need for mental health treatment in the tough-guy environment of football.

“Sometimes you’ve just got to put your pride aside and know when enough is enough. Sometimes you’ve got to take it upon yourself and know when ... you can’t handle it,” Griffen said.

Griffen was a full participant in the workout, but coach Mike Zimmer said the decision about whether he’d play for the Vikings (4-2-1) on Sunday night against the Saints would be made at the end of the week.

Griffen was taken to a hospital Sept. 22 after a scary series of incidents around the Twin Cities.
