Norwich held on for a  vital 1-0 win over Bournemouth at Carrow Road after both sides were reduced to 10 men and Paul Tierney became the first Premier League referee to use a pitchside monitor
The hosts were on top during the opening period but failed to make it count until Steve Cook received a red card for acrobatically palming away a shot in the area from Norwich debutant Ondrej Duda on the half-hour mark
Teemu Pukki coolly converted the resulting penalty and the game maintained pace and controversy, culminating with a reckless lunge on Callum Wilson from Norwich defender Ben Godfrey, prompting Tierney to check the pitchside monitor
The initial yellow card was overturned and the centre-back was issued with his marching orders as tempers began to flare on both sides
With both teams down to 10 men, Bournemouth regained some attacking momentum but the Canaries held on to close the gap to safety to six points
Norwich deserved the three points and were controlling the game before Pukki slotted home his spot-kick down the centre of the goal as Aaron Ramsdale dived to his right
But the game will be remembered for the two sending offs, with Cook's lunging save to stop Duda's goalbound shot worthy of any Premier League goalkeeper, and he left the field without question as his instinctive effort was punished
Cherries boss Eddie Howe immediately called Simon Francis into action in place of Harry Wilson to maintain his four-man defence, but the Norwich onslaught ramped up and Ramsdale produced a number of saves to keep his side in the game
All eyes were on the referee again midway through the second half, as replays revealed how Godfrey's mistimed tackle on Callum Wilson was clearly a red-card offence, resulting in the first use of a pitchside monitor and the initial yellow card upgraded to a red
With the playing field level, Bournemouth were revitalised and looked to press Norwich into their own half to salvage a much-needed point, but Howe's side will rue several big misses, with Callum Wilson spurning two clear-cut chances
Both teams finished the afternoon where they started in the table, but Norwich boosted their chances of survival with a positive performance which slashed the gap to safety, while Bournemouth's slump continues and they are just three points ahead of the Canaries in 19th with 10 defeats from 12 games
Bournemouth struggled to cope with the inventive duo of Buendia and Todd Cantwell, but it was the Argentinian's through-balls and menace that wreaked havoc, creating four chances before leaving the field in stoppage time
