With Johnnie Dyer, Eddie Smith and the Harris brothers missing through injury, Slough were boosted by the return of Darryl Thomas to the starting eleven after a bout of flu, whilst Luke Knight made his first start.
Slough started the better, with Cornell heading over before hesitation from Histon goalkeeper Ordonez led to Thomas hitting the bar after Cornell’s layoff.
Ordonez then made a good save from Thomas as the striker was played in on goal, but failed to get enough power or accuracy on his finish.
Slough did make the breakthrough on 23 minutes though, and predictably James Dobson had a big hand in the build-up. Dobson received the ball out wide on the left and whipped in a superb ball, which was finished into the bottom corner by Cornell at the second attempt.
Minutes later, Histon were reduced to ten men as Charlie Saunders was dismissed after kicking out at Dobson. The visitors gave Slough a few scares at the back, but the Rebels defended well and Jake Somerville remained untested. The home side looked likelier to find the next goal, with both Cornell and Dobson forcing Ordonez into saves.
Slough’s slender lead never looked likely to be enough, and the Rebels felt they should have had a penalty early in the second half, but the referee was unmoved as Cornell had his shirt tugged in the box.
The Rebels continued to play neat football without penetrating the Histon defence enough, and the Cambridgeshire side improved as the game went on. Eugene Libeatucci tried for the top corner from 25 yards, but Somerville spectacularly tipped the ball over.
Both sides went agonisingly close, with Jamie McClurg turning Dobson’s cross wide, and Histon hooking a shot off target at the near post from a corner.
Slough looked short of ideas and unable to kill the game off with a second goal against the ten men of Histon, and their problems worsened when Cornell limped off to be replaced by debutant Jamal Branker.
Moments later, the visitors were awarded a penalty after a shirt-pull, and Nick Freeman levelled from the spot to punish Slough for their wastefulness in front of goal.
George Short was then shown the red card after a second late tackle, followed by Histon full-back Harry O’Malley, also for a second yellow card, but neither the ten men of Slough nor the nine of Histon could find a winning goal in the rain at Holloways Park.
Reece Yorke fired a long shot wide in the dying seconds, but the frustrated Rebels had to settle for a point.
