Mark Robins' side make the short trip to Nuneaton Town's Liberty Way stadium, with League One side MK Dons their fourth opposition this Pre-Season...
The Sky Blues have featured against Sutton United, Valenciennes and Barnsley, with Mark Robins expecting another tough challenge from the visiting Dons tomorrow night.
He said: "It's going to be another tough game against a team from a higher division. That is the way we wanted to prepare so we can see where we're at.
"It's another physical challenge for everybody and hopefully we can have a better outcome because thigns are started to get a little wrapped up now for the start of the season."
The Sky Blues also took a side to Premier League Southampton for a behind closed doors friendly at the Saints' Staplewood training ground.
Southampton ran out 2-0 winners, but with established first-team regulars such as Manolo Gabbiadini, Charlie Austin, Shane Long and Maya Yoshida featuring, it was a good test for a young Sky Blues side.
"We played yesterday against Southampton at their training ground and first-team members were included in their squad, so it was really beneficial to those who travelled.
"It was a great workout for us, and a decent workout for them as well. The training ground was magnificent and the players got to see how the Premier League players train and are treated,"
He added: "It was a really good experience, but it also gave us a chance to test ourselves against them and see how physically fit they are, what sort of shape they're in and how hard they work."
