The Sky Blues head to Stadium:MK to face League One side Milton Keynes Dons in the fourth round of the Emirates FA Cup.
Coventry knocked out Premier League Stoke City at the Ricoh Arena in round three with Jack Grimmer cutting inside and beating England International Jack Butland at his near post to secure the victory.
MK Dons too defeated higher opposition, beating Queens Park Rangers 1-0 at Loftus Road, but have since parted company with Robbie Neilson and this week announced former England U16s boss Dan Micciche as his replacment.
The Dons will be without star-man Chucks Aneke after he picked up straight red card in his sides 2-1 defeat to Northampton Town a fortnight ago.
The Sky Blues one the other hand have no new injury concerns ahead of the trip. Liam Kelly remains a doubt despite returning to full training this week. Jodi Jones (ACL) and Tony Andreu (ACL) both continue their fight-backs.
Tallisman, Dean Lewington has been at MK Dons since before they became MK Dons. The Wimbledon academy graduate made his first appearance in 2003 and has been at the club ever since, racking up 684 appearances along the way.
With Chucks Aneke suspended, Keiran Agard will be MK's main attacking threat. The former Bristol City man may have only found the net four times this season but has ejoyed prolifc spells with Rotherham and Yeovil, scoring 26 goals in the 2013-14 season.
Two stunning free-kicks from debutant Chris Maguire fired the Sky Blues to victory at Stadium:MK infront of 7,000 city fans.
Shaun Williams gave the home side the lead in the first half from the spot but that was soon cancelled out after the break when Chris Dagnall's deflected effort looped over the keeper and in.
The scoreline remained level until the final five minutes, when Chris Maguire, on-loan from Sheffield Wednesday, stepped up to curl a stunning 25-yard free kick over the wall and into the bottom corner.
However, he wasn't done there. In added time he secured the three points when, this time from 30-yards, he looped the ball over everybody and into the far top corner sending the 7,000 strong Sky Blue army wild.
