Coventry City have now gone four games unbeaten after securing a point courtesy of a goalless draw away against Colchester United.
It was a creditable result for Iain Dowie's men against a Colchester side who have lost only once in their last 16 home games.
The result also means that the Sky Blues are unbeaten since Dowie took over.
Iain Dowie named an unchanged side for the trip to Layer Road.
There was one amendment on the bench, with club captain Robert Page returning to the 16 at the expense of Che Bunce.
Geraint Williams' side had the first real chance of the game on six minutes when Duguid's cross found Cureton, who crossed into the danger area. However, Duguid was adjudged to have been fouled in the build-up to the chance and from the resulting free-kick, the home side won a corner.
The set-piece found Chris Iwelumo, who saw his shot blocked by Elliott Ward just in front of goal. The ball was put back into the danger area by Kemi Izzet for Cureton, but he couldn't get the better of Marcus Hall, who cleared the danger.
The Sky Blues had a chance in the 21st minute, when Leon McKenzie headed towards goal, only for Wayne Brown to head over his own crossbar.
But Colchester had an even better opportunity on 26 minutes when Izzet hooked the ball forward for Iwelumo - only for the Scot to see his first-time volley fly inches wide of the right upright.
Adebola headed into the arms of Gerken on 41 minutes, before Virgo was forced to head over his own crossbar from Cureton's cross moments later.
After both sides emerged for the second half, Iwelumo blasted over Marshall's goal two minutes after the break, before Kevin McLeod's cross sailed across the danger area, much to the relief of the Sky Blues.
Stephen Hughes produced City's best chance of the game on 55 minutes when his powerful drive was tipped over the bar by Gerken, before from the resulting corner, Tabb's shot sailed wide. There was even a penalty shout in the melee from the corner, with Brown appearing to go through the back of Hawkins.
Cureton and Duguid both had shots blocked as the Sky Blues defended resolutely, before at the other. McKenzie shot wide after turning well.
It was to be McKenzie's last contribution in the game, with the forward replaced by Michael Mifsud on 69 minutes.
Coventry pressed through Adebola and Tabb but couldn't find the killer ball before the big striker headed wide while Hughes also shot just past the target as the Sky Blues pressed.
