Millwall goalkeeper Liam Roberts has had a ban for his dangerous challenge on Crystal Palace striker Jean-Philippe Mateta last weekend extended to six matches.
The FA had appealed for a longer punishment, with the straight red card issued to Roberts triggering an automatic three-match ban.
A regulatory commission has now backed the FA and ensured the stopper will miss another three games.
Millwall said they were “disappointed with the outcome” but “respected the process that has been undertaken”.
In a statement, Roberts said: “As the dust settles, I want to address what has been a really difficult week for all concerned, including my family and I.
“Firstly, to Jean-Philippe, who I continue to send my best wishes to in his recovery. As soon as I could, I reached out to Jean-Philippe personally to apologise, and I was thankful to hear back from him that evening that he was OK and reassured me not to worry.
“I am devastated by what happened. I unequivocally accept the red card as awarded and accept my punishment. Furthermore, it has been extremely unpleasant to observe suggestions that I intended to harm a fellow professional.
“I have categorically never stepped onto a football pitch with the intention of hurting anyone.”
Roberts revealed that he had received an “unthinkable amount” of abuse and threats towards his family, which he attributed to “misleading articles and comments”.
Longest Premier League bans for on-pitch offences
All bans handed out by the FA
Eric Cantona (Man Utd) – nine months: He kung-fu kicked a Crystal Palace fan. Doesn’t really require more detail.
Joey Barton (QPR) – 12 matches: Before Sergio Aguero scored the most famous Premier League goal ever, Barton had been sent off for elbowing Carlos Tevez in the head, before kicking Aguero and almost headbutting Vincent Kompany.
Paolo Di Canio (Sheffield Wednesday) – 11 games: You just can’t push over a referee, as Di Canio did to Alcock.
Luis Suarez (Liverpool) – 10 games: Biting is bad kids, a lesson Suarez found out on numerous occasions – including this one on Branislav Ivanovic – but never really seemed to learn.
David Prutton (Southampton) – 10 games: Another push on a referee, this time on Alan Wiley in 2005.
Referee Michael Oliver initially only showed Roberts a yellow card, but that was overturned by VAR. Oliver has not been appointed to a match this weekend.
Mateta was given oxygen on the pitch before being carried off on a stretcher and taken to hospital in an ambulance. The 27-year-old needed 25 stitches for a severe laceration to his left ear.
Millwall had issued a strong defence of Roberts, accusing “certain news organisations” of an “unwarranted character assassination of Liam”.
They added: “No player at Millwall Football Club steps on to the pitch with the intent to harm another, and the club will continue to support Liam, who reached out to Jean-Philippe personally on Saturday evening with an apology which was accepted immediately.”
Millwall’s statement came after Palace chairman Steve Parish described the incident as the “most reckless challenge” he had ever seen on a football pitch.
He also said that Roberts should have a “long, hard look at himself” after endangering a fellow professional.
Palace manager Oliver Glasner added: “I’m pretty sure he didn’t want to injure JP in this situation, but I also think that you have to decide when you make such an impact, you just can’t do it in this way.”
Roberts has made six appearances for Millwall since signing on a free transfer from Middlesbrough last summer and has generally deputised for regular starter Lukas Jensen, who came on as his replacement at Selhurst Park.
