After sustaining a serious anterior cruciate ligament injury almost a year ago against Egham Town, Foulser underwent reconstruction surgery and has been on the path to recovery ever since, culminating in his late introduction in place of Billy Jeffreys from the bench.
By that time, Redditch had gone four goals ahead and were certain of all three points after a second half collapse from the Rebels, who are still struggling badly for goals.
After both sides observed a minute's silence following the death of Redditch supporter Derrick Mutton, the game got underway, with Slough having early chances.
First, Tom Moran headed over from a free kick, and Eddie Smith was thwarted by Sam Hornby after breaking though. From the resulting corner, Scott Harris acrobatically shot over the bar.
A slip from Sean Fraser let in George Carline down the right, but his shot was held by Luke Williams, and Daniel Scarr headed wide from a free kick which was played to the back post.
Despite passing the ball around nicely and exerting pressure in the Redditch half, Slough lacked the ability to find a final ball, and went a goal behind nine minutes before the break.
Williams did well initially to keep the ball out after the ball took a huge bobble off the turf, but Carline was on hand to tap in the rebound.
Slough were perhaps unlucky to be trailing at the interval after what was a fairly even first half, but almost immediately after kick-off in the second period, Redditch scored their second. The ball fell invitingly for substitute Courtney Baker-Richardson on the edge of the box, and he planted the ball beyond Williams within 25 seconds of the restart.
Redditch had another effort chalked off after the referee spotted a foul, but the hosts made it 3-0 on 55 minutes through Ashley Sammons following a break by the hosts. Slough had appealed for a back-pass at the other end, but in vain.
Just five minutes later, Slough’s afternoon got worse with Redditch scoring a fourth. This time, Simeon Maye was on hand to prod the ball home, seizing upon a goal-bound strike which had beaten Williams. Joint manager Neil Baker commented after the game that his side had been ‘ragged’ for the first 20 minutes of the second half, and that they must dig deep to find form and results.
Redditch went close to a fifth, with Williams pulling off a good save to deny Sammons, and the resulting corner was cleared off the line.
Slough struggled to respond, George Short’s off-target strike being as close as the Rebels came to a goal, and Redditch spurned the opportunity to score again as Carline blasted a penalty kick wide of goal, with Williams having guessed the right way.
Late on, Smith sent a tame header straight into the arms of Hornby from James Dobson’s cross, but the Rebels again failed to get on the score sheet.
