Coventry City U23's were beaten 2-1 at home by Birmingham City.
City should have been ahead when Jordan Ponticelli clipped a Jordan Shipley cross onto the underside of the bar in the fourteenth minute and at the end of the first half when Jordan Shipley headed a Jacob Whitmore cross over.
Five minutes into the second half and Birmingham had a corner which was not defended properly and McCoy scored from close range.
Four minutes and it was two when Addai saved from McCoy and the loose ball fell to Wes McDonald who drove in from eight yards.
With sixteen minutes to go, Tom Bayliss started a run in his own half and skipped past man after man before thumping it into the net.
Birmingham controlled things from then on and it was a defeat.
