A goal just after half-time from Danny Hylton was the difference as ten man Luton beat Chesterfield at Kenilworth Road.
Hylton struck when he received a through pass before beating Joe Anyon, to give Luton their third win in as many games as they saw off a managerless Spireites side who sacked manager Gary Caldwell last weekend.
The Hatters had been in an awkward final half quarter after midfielder Pelly Ruddock Mpanzu was shown a straight red card for a high challenge on Andy Kellett. But despite that, the hosts had the better of the late chances, with Harry Cornick hitting a post and James Collins seeing two efforts miss the target.
Chesterfield’s best chance saw Louis Reed head wide, while in the first half, but struggled to make their extra man count after the dismissal.
The result is enough to move Luton into 3rd spot in the League Two table after 9 matches, with the team looking to continue their promising start as they travel to Morecambe in their next outing.
