Rasmus Hojlund’s injury time goal grabbed a point for Manchester United as 10-man Bournemouth suffered a blow to their hopes of European qualification.
Andoni Iraola’s men looked set for victory thanks to Antoine Semenyo’s 11th goal of the season midway though the first half.
But the contest turned on a controversial decision to upgrade Evanilson’s 70th-minute challenge on Noussair Mazraoui from a yellow card to a red following a video assistant referee (VAR) review.
Evanilson appeared to slip as he closed down the United defender but referee Peter Bankes upgraded his initial yellow card, meaning the Brazilian must now serve a three-match ban.
United piled forward looking for an equaliser and after Mason Mount’s shot had been deflected wide, Hojlund turned Manuel Ugarte’s effort home from close range after the Uruguay midfielder had been set up by Luke Shaw.
The result lifts Ruben Amorim’s side to 14th in the Premier League but, in truth, their sights are fully trained on Thursday’s Europa League semi-final first-leg trip to Athletic Bilbao.
But the goal is devastating for Bournemouth, who remain below Fulham and Brighton in the quest for an eighth-place finish which would secure a spot in next season’s UEFA Conference League if Crystal Palace don’t win the FA Cup.
