Chesterfield fought out a goal-less draw with Coventry City in a game which saw the Spireites reduced to ten men when Robbie Weir was sent-off.
The first half saw chances where either side could have gone ahead with Peter Vincenti twice going close for the visitors.
Both of his opportunities were free headers, the first when he headed over from a corner before again heading off target after Jodi Jones got down the right.
The Spireites also had chances of their own. Jordan Flores went closest on 34 minutes as his free-kick was well-saved by Lee Burge.
Kristian Dennis also threatened to score. He seized on a loose ball at the back from Jack Grimmer, but saw his snap-shot kept out.
Neither side could break each other down sufficiently in the first half though, with most of the attempts at goal coming from long range.
Coventry's Marc McNulty struck a tame effort after 13 minutes straight at Lee, before forcing the Chesterfield keeper into making a harder stop with an excellent dipping volley.
Meanwhile Chesterfield had efforts from outside the box also saved. Matt Briggs was kept out in the opening 20 minutes whilst Dennis failed to really trouble Burge with a curling shot.
The major talking point of the game came in the second half when, with an hour on the clock, Spireites midfielder Weir was sent off. He received his first yellow card for bringing down Jones at the start of the second period, before being given his marching orders for a trip on the same Sky Blues player on 60 minutes.
Before that, Lee made a spectacular save which ultimately earned his side a point, as McNulty's ferocious effort was tipped onto the bar and behind.
The hosts struggled to create following the red card, and their only chance in the second half came from the boot of Chris O'Grady, who dragged his shot wide from the edge of the area on 64 minutes.
Weir's dismissal invited Coventry pressure and they went close on multiple occasions. They looked to have found a winner with just over ten minutes remaining, only for it to be disallowed after Vincenti headed home but was deemed offside.
McNulty, meanwhile, spurned a brilliant chance one-on-one, and then missed an even simpler opportunity, heading wide from a matter of yards out when it looked easier to score.
Chesterfield went desperately close to scoring a dramatic late winner through substitute Gozie Ugwu. Deep into injury time he got in behind and into the penalty area, but just as he was about to pull the trigger, he was denied by a Sky Blues defender. The resulting corner from Ugwu's blocked shot was then headed over by Ian Evatt with the last touch of the game.
Chesterfield: Lee, Wiseman, Hird, Evatt, Jules, Dennis (De Girolamo 79), Flores, Weir, Reed, Briggs (Kellett 66) O'Grady (Ugwu 72).
