Martinez's hair-pulling red card and Maguire's additional ban leave United without both starting centre-backs for crucial Chelsea clash.
Manchester United will face Chelsea without both starting centre-backs after Lisandro Martinez received a straight red card for hair-pulling and Harry Maguire faces an additional ban for swearing at officials.
The defensive crisis threatens to derail United's Champions League qualification hopes with six games remaining in the season.
Martinez will miss three matches for violent conduct after grabbing Dominic Calvert-Lewin's man bun during Monday's 2-1 defeat to Leeds. The Argentine was dismissed in the 56th minute with United already 2-0 down.
The suspension rules out Martinez for crucial fixtures against Chelsea, Brentford and Liverpool.
Harry Maguire faces an additional one-match ban beyond his standard red card suspension from the Bournemouth match. The FA is set to punish Maguire for swearing at fourth official Matt Donohue following his dismissal at the Vitality Stadium.
Interim manager Michael Carrick must now devise a defensive solution with both first-choice centre-backs unavailable.
The 2-1 loss marked United's first league defeat to Leeds since 1981, adding historical significance to an already damaging result.
Martinez was making his first Premier League appearance since 10 February after returning from injury, only to last 56 minutes before his controversial dismissal.
Referee Paul Tierney brandished the red card after VAR advised him to review the incident on the pitchside monitor. Replays showed Martinez grabbing Calvert-Lewin's hair while jostling for position, pulling out the striker's hairband in the process.
The incident sparked fierce debate across football media and punditry.
Guardian correspondent Jamie Jackson defended the decision on talkSPORT's Inside Devils programme:
Two reasons, first of all he pulls his hair, everyone keeps on saying, 'He was just grappling for something and it just happened,' no, I don't buy that. But also, have a look back at the incident, he twice goes for the hair, the first time he didn't get it, second time he grabs it, so for me, it's pre-meditated.
talkSPORT's Angelina Kelly agreed with the violent conduct ruling:
It's violent conduct! It is violent conduct to yank someone's hair. Have you seen those stills? He has hold of it.
Host Flex mounted a passionate defence of Martinez, arguing the decision represents football's over-sanitisation:
This is a physical game, this is a contact sport, and last time I checked, the Premier League was supposed to be the biggest advocate for physical, front foot, dominant football, where there is contact. And we have now reached a stage where they have sanitised our game so much, I don't recognise it any more.
Flex cited IFAB Law 12: Fouls and Misconduct, which states hair pulling is violent conduct only "if done with force and aggression".
The Martinez incident highlights growing inconsistency in how officials interpret physical contact. Normal jostling between defenders and strikers now risks red cards if any contact occurs with an opponent's hair.
The debate extends beyond this single incident to fundamental questions about football's physicality.
Critics argue VAR's microscopic analysis transforms routine physical battles into potential red card offences. The Premier League's reputation as football's most physical league faces erosion through:
Flex proposed a controversial solution during the talkSPORT debate:
Tie it [long hair] up. That's another thing, get the durags out, it's a hazard [long hair]!
While provocative, the suggestion highlights how current rules create situations where hairstyles become tactical liabilities.
More substantive reforms could include clearer definitions of "force and aggression" and guidance that distinguishes between deliberate violent acts and incidental contact during normal play.
United face an uphill battle to secure Champions League qualification without their defensive partnership. The Chelsea match becomes pivotal with both teams fighting for top-four positions.
The broader debate about officiating standards will intensify as similar incidents arise. The Premier League must address whether its current interpretation of violent conduct aligns with the physical football that defines English football's global appeal.
For United, the immediate challenge is finding defensive solutions while their appeal against Martinez's suspension appears unlikely to succeed.
