Bermudian striker Nahki Wells continued his return to top form by claiming his 22nd goal of the season but promotion-seeking Bradford City were held at a 2-2 at Chesterfield after twice leading in their English League Two match on Saturday.
The draw helped Bradford hold on to the final play-off place one point ahead of Exeter City, who were also held 2-2 after twice leading at AFC Wimbledon.
Wells, 22, the club's leading scorer, fired the Bantams ahead in the 36th minute from 15 yards -- his fourth goal in three matches after a two-month drought.
Tendayi Darwikwa equalised for the hosts on 70 minutes from Marc Richards' cross, but the Bantams went ahead again when Ricky Ravenhill's drive found the net nine minutes later.
However, Sam Togwell levelled the scores in injury time to keep Chesterfield's own hopes of reaching the play-offs alive.
Chesterfield, nicknamed the Spireites, are now four points behind seventh-placed Bradford with both sides having three games to play.
Exeter have two games left.
