The New York Stadium will open it's turnstiles on Tuesday 14th August from 11am to allow fans to go along and see the new squad in action.
There will be the opportunity to look round the ground, take photographs and for the youngsters to have autographs signed.
Boss Steve Evans told the clubs website: "I want to give the fans a chance to see us train, we are proud to be a part of this community.
“We talk a lot about how lads perform on the training pitch and this is their chance to see it for real. We’ve picked a date during the summer holidays, allowing the youngsters who are off school to come down, and with free entry it’s a perfect opportunity which I’m hoping as many as possible will take advantage of.”
The players will be on show from 11.30am and the club advise people to arrive early.
The Millers complete their pre-season fixtures on the same evening when they head to Kettering for a 7.45pm kick off.
