Burnley produced a critical victory at Huddersfield Town on Wednesday night.
The Clarets' win, their second in three days, was sealed when Ashley Barnes slotted home midway through the second half from Ashley Westwood's pass.
Huddersfield had taken the lead through Steve Mounie's header in the 33rd minute but conceded an equaliser and had Christopher Schindler sent off within two minutes before half-time.
Wood met Dwight McNeil's low cross from the left six yards out and swept in for his fifth goal of the season.
Schindler, who had earlier been booked for a foul on Wood, was then shown a second yellow card for hauling down McNeil on the edge of the penalty area.
Defeat means bottom-of-the-table Huddersfield are eight points from safety.
