Rotherham United saw two efforts cleared off the line, as they were held 0-0 by a resilient Cheltenham side at Don Valley Stadium.
Pablo Mills and Nick Fenton were both denied by excellent clearances, but the despite not being able to break down the Robins, the Millers moved a point closer to securing a guaranteed play-off place.
Ronnie Moore was forced into one change, with Mark Lynch replacing the suspended Danny Harrison.
Mills started the game in midfield, and created the first chance on three minutes; his ball over the top found Adam Le Fondre, who couldn't get the ball under the control in the area, allowing Shane Duff to make the tackle.
Kevin Ellison and Marcus Marshall combined on the right, before Ellison cut inside, but his shot was comfortable for Scott Brown in the Robins' goal.
The visitors had two attempts from set-pieces, but Justin Richards blazed the first over the bar, and headed into the side netting four minutes later.
Marshall went close from the Millers first corner of the game, and when Rotherham found themselves in a two on one situation on the counter attack shortly after, Nicky Law was controversially flagged offside.
Just minutes later, two contenders for comedy moment of the season came during the same passage of play. Brown misjudged a back-pass from Duff, allowing Milers top scorer Adam Le Fondre to capitalise, and as he squared for Ellison, the winger slipped from 12 yards out.
The best chance of the half fell on the half hour. Law burst into the area from the right hand side and squared for Le Fondre, whose side footed effort was deflected wide. From the resulting corner, Mills' speculative effort from 35 yards wasn't likely to trouble the Robins' goal. Marshall forced a save from Brown moments later, as the Millers pressed for an opener.
The last chance of the half came from Ellison, who fired wide from the edge of the area following some good work on the left by Marshall.
Millers 0-0 Cheltenham
The second half began much the same as the first, and Ellison almost capped a fine Millers move with a rasping half volley from the edge of the area. Law picked up the ball in his own half, before finding Josh Walker in the centre circle. His cross-field ball was headed down by Ellison to Le Fondre who returned the favour, but the winger's effort was just over Brown's crossbar.
Cheltenham's first chance of the half came from a free-kick on the edge of the area, but Michael Pook fired over the bar.
Mills came closest to opening the scoring with just under half an hour remaining. After peeling off his defender at the back post from Law's corner, his shot was blocked on the line by Cheltenham forward Justin Richards.
Ellison, now operating up front was found with a clever pass by Mills from midfield, and his shot on the turn was deflected just over for a corner.
With their first meaningful attack of the half, Cheltenham almost took the lead. Josh Low got the better of substitute Jamie Green on the right-hand side, and when the ball found Medy Elito in the area, his side-footed shot was cleared off the line by Ian Sharps. At the other end Le Fondre glanced wide a header from Abdulai Bell-Baggie's cross.
Five minutes were indicated by the fourth official, and Millers hearts were in their mouths as Julian Alsop met Matt Thornhill's cross, but his header was narrowly over the bar.
Rotherham were awarded a free-kick with seconds remaining, and when the ball fell to Craig McAllister 15 yards out, his curling shot was tipped just wide by Brown. The resulting corner saw Fenton have a header cleared off the line, with the last action of the game.
