Our Sky Bet League Two fixture away at newly-promoted Lincoln City on Saturday 16 September has been brought forward to a 1pm kick-off, the club can confirm.
The decision was reached following police advice.
Stags last faced Lincoln in a competitive game in February 2013, as Mansfield recorded a 1-0 win at Sincil Bank.
Meanwhile, The Stags' Checkatrade Trophy Group G match against Lincoln will take place at One Call Stadium on Tuesday 29 August (7.45pm). Ticket prices will be £10 adults and £5 concessions.
