Dele Adebola's second goal in as many matches sealed a point for Coventry as they drew 1-1 with Preston North End.
The big striker showed his composure to strike ten minutes before the final whistle to cancel out David Nugent's first-half opener for Paul Simpson's men.
Micky Adams named an unchanged side as the Sky Blues made the trip to Deepdale.
Coventry City's manager kept faith with the team which beat QPR 1-0 at Loftus Road on Saturday - the only change coming on the bench, with the fit-again Stern John replacing Rafa Gonzalez.
Preston make one change, with Tommy Miller making his first start for Paul Simpson's men since signing on loan from Sunderland two weeks ago. He replaced the injured Matt Hill.
Both teams played some good attacking football in the opening 15 minutes, with Adebola and Nugent looking to find the killer touch for their respective side. However, the home side were forced to make a change after 15 minutes when Sean St Ledger was replaced by Kelvin Wilson - the former still suffering the effects of an earlier clash with Leon McKenzie.
Adebola went into the book for an alleged foul on 25 minutes, before three minutes later, Cameron hit the ball hard and low from 20 yards but unfortunately into the arms of Carlo Nash.
The action soon switched to the other end and Richard Duffy put the ball perilously close to his own goal from a Preston cross, before the Sky Blues cleared the danger from the corner.
Agyemang hit a chance wide on 33 minutes, but Preston made the breakthough just seconds later when Nugent headed in a Danny Pugh cross. It was tough on Coventry, who had defended resolutely throughout the half and for Andy Marshall, who got a hand to the shot but couldn't quite keep it out of his goal.
And the Sky Blues custodian had to be alert against with 37 on the clock - Marshall making a fine save at the near post from Simon Whaley's in-swinging shot.
It could so easily have been 1-1 at the half-time whistle as Cameron's shot was deflected inches wide of the target, before Adebola painfully missed in the middle from the resulting corner.
Preston started the second half as the brighter of the two sides and with 54 on the clock, Nugent could have had another when he pulled his shot inches wide of the upright.
Currie showed good endeavour before shooting at the keeper before at the other end, Marshall made an excellent save from a fierce curling shot from Agyemang.
Adams made a double substitution on 68 minutes, with John replacing McKenzie and Jay Tabb replacing Cameron.
John was at the centre of controversy just minutes later when the Trinidadian appeared to have his legs taken when he was lining up to take a shot, but the referee waved play on and Coventry were back to the drawing board.
John headed over from a Hall cross and the Sky Blues had the lion's share of possession, before Elliott Ward became the second Coventry City player to go into the book on 75 minutes for a handball.
The Sky Blues made their third and final substitution on 78 minutes when Kevin Kyle replaced Duffy and in the 80th minute, the hard work paid off.
It was no surprise that it was Adebola who was again the provider - the striker holding off his man and turning inside before finishing into the bottom corner to provide City with their just rewards.
