Forest Green Rovers' kit supply issues mean MK Dons will wear their red away kit at Stadium MK on Saturday when the sides meet.
Rovers parted ways with Hummel after they were let down with supply of their kits and switched to PlayerLayer a little over two weeks ago.
However, they still only have one kit available to use, and with fears of a clash this weekend, MK Dons have agreed to wear red and gold at home instead of their usual white and gold.
MK Dons manager Paul Tisdale said: "We're wearing red – there has been a quirk in their kit colours so anyone coming on Saturday, wear red and support the team!"
Dons wore the red kit at home earlier this summer in their pre-season friendly against Ipswich Town.
