Chelsea were in dire straits and Jackson saw red in the 36th minute as his moment of madness encapsulated their haphazard start.
The forward led with his elbow as he crashed into Newcastle defender Botman, initially earning a booking that was upgraded to a dismissal after VAR called for a check.
Newcastle took a huge step towards qualifying for the Champions League as Sandro Tonali inspired a vital 2-0 victory over top five rivals Chelsea on Sunday.
Tonali put Newcastle ahead after just two minutes at St James’ Park before Chelsea striker Nicolas Jackson was sent off for an elbow on Sven Botman late in the first half.
Bruno Guimaraes struck in stoppage-time to secure the Magpies’ seventh win from their last nine league games and lift them into third place in the Premier League.
Eddie Howe’s side, aiming to feature in the Champions League for the second time in three seasons, are one point above fourth-placed Manchester City and three clear of fifth-placed Chelsea and sixth-placed Aston Villa.
League Cup winners Newcastle travel to Arsenal next weekend before hosting Everton in their last two matches.
Chelsea’s first defeat in seven league games leaves their bid to return to Europe’s elite club competition in jeopardy.
Seventh-placed Nottingham Forest will move one point above Chelsea and knock them out of the top five if they beat relegated Leicester at the City Ground later on Sunday.
With Manchester United at home and Forest away left on their schedule, Enzo Maresca’s team face a tense finish to their top five challenge.
Reaching the UEFA Conference League final against Real Betis with a win against minnows Djurgarden on Thursday was little consolation to Chelsea after this damaging result.
Newcastle made the perfect start after just two minutes with a blistering break that caught Chelsea cold.
Countering from a Chelsea corner that came to nothing, Newcastle’s Anthony Gordon was felled by Moises Caicedo.
When the penalty appeal came to nothing, Jacob Murphy whipped in a low cross that Tonali converted at the far post.
Swept along by the tidal wave of emotion rolling down from the stands, Newcastle poured forward in search of a second goal.
Alexander Isak miscued with the goal at his mercy after Dan Burn headed down Tonali’s free-kick.
Caicedo, deployed at right-back rather than his usual midfield role, was being tormented by Gordon as Newcastle pinned the Blues back.
Maresca sent on Reece James for Noni Madueke at half-time in a bid to remedy Chelsea’s defensive issues, but the right-back nearly conceded an immediate penalty with a shoulder barge on Gordon.
Unmarked from a Newcastle corner, Isak wasted another good chance with a wayward volley.
Chelsea finally forced Nick Pope to make a save when Marc Cucurella took Cole Palmer’s pass and unleashed a powerful effort that the keeper palmed away.
That near-miss was part of a period of sustained Chelsea possession despite their numerical disadvantage.
Picked out by Jadon Sancho, Enzo Fernandez’s drive forced a superb save from Pope in the closing stages.
James should have rewarded Chelsea for their late barrage but he headed wastefully over from an unmarked position.
Howe’s anxiety was palpable on the touchline and Guimaraes finally eased the nerves in the 90th minute.
Burn’s pass found the Brazil midfielder, whose shot took a hefty deflection as it looped in over Chelsea goalkeeper Robert Sanchez.
Moises Caicedo Lone Goal Helps Chelsea Defeat Stubborn Pafos On Liam Rosenior UCL debut—-Moises Caicedo’s late goal gave Chelsea a vital 1-0 win against Cypriot minnows Pafos on Wednesday as the Blues moved closer to automatic qualification for the Champions League last 16.
In Liam Rosenior’s first Champions League game as Chelsea boss, Caicedo netted in the closing stages at Stamford Bridge to end Pafos’ stubborn resistance.
Chelsea’s fourth victory from seven Champions League group stage matches lifted them into eighth place.

A win at Napoli in their final group game on January 28 would likely be enough to send Chelsea through to the last 16, depending on other results.
The Blues would face the unwanted stress of a play-off round if they finish outside the top eight.
Rosenior has won three times and lost once in his first four games since arriving from Strasbourg to replace Enzo Maresca, who left Stamford Bridge after mounting tensions with the club’s hierarchy.
It was far from plain sailing for Rosenior as Chelsea struggled to find a way past inspired Pafos keeper Jay Gorter before Caicedo made the breakthrough.

Optimistic Chelsea fans have noted their two Champions League triumphs in 2012 and 2021 came after they changed manager in mid-season.
But there is a long way to go before Rosenior can hope to emulate those iconic victories masterminded by Roberto Di Matteo and Thomas Tuchel.
Chelsea have been steady rather than eye-catching so far under Rosenior, with far sterner tests lying in wait in the surprise choice to replace Maresca.
Wake-up call
Rosenior made six changes from the 2-0 win over Brentford on Saturday, with injured England forward Cole Palmer absent due to a slight strain.
Brazilian veteran David Luiz, a 2012 Champions League winner with Chelsea, was on the bench for Pafos, who were far from overawed in their first ever match against English opposition.
Chelsea laboured for long periods and even when Enzo Fernandez had the ball in the net in the 18th minute, the midfielder’s close-range header was disallowed for a push.

Chelsea nearly gifted Pafos a shock opener when a wayward back-pass to Filip Jorgensen was almost intercepted by Anderson Silva, but the Blues keeper chested the ball away from danger.
Rosenior’s men had lost their momentum and Pafos went close when Jaja’s shot from just inside the area took a wicked deflection off Reece James and hit the post with Jorgensen rooted to the spot.
That near-miss served as a wake-up call and Caicedo’s blast was pushed away by Gorter before Benoit Badiashile glanced a header narrowly wide moments later.
Caicedo’s long-range drive forced another good stop from Gorter, who also repelled Jorrel Hato’s fierce strike just before half-time.
Frustration was mounting among Chelsea supporters and Rosenior made a double change at the break, sending on Robert Sanchez for Jorgensen and Estevao Willian for James.
Estevao nearly made an instant impact with a stinging volley that Gorter saved at full stretch.
Gorter was enjoying the game of his life and he denied Pedro Neto and Caicedo with two more fine saves.
To Rosenior’s immense relief, Chelsea finally found a way past Gorter in the 78th minute.
Pafos couldn’t clear a corner and Caicedo arrived to flick his header into the far corner from close range.
The winning goal came in the 94th minute, scored by Pape Gueye, securing Senegal’s triumph in a match filled with tension and controversy.
The game was briefly overshadowed by an on-field protest from the Senegalese players.
Earlier in the match, a goal by Senegal was disallowed, sparking visible frustration. The situation escalated when the referee awarded a penalty to Morocco, prompting the Senegalese squad to walk off the pitch in protest.
Officials intervened, temporarily halting the match to restore order.
After a tense pause, Senegal returned to the field, and Morocco ultimately missed the penalty, leaving the scoreline unchanged.
Gueye’s strike moments later sealed victory for Senegal.
The final sparked heated debate among fans and pundits, with the disallowed goal and controversial penalty highlighting the intensity and drama of this AFCON showdown.
