Farrell went on to kick a game-winning drop-goal at Gloucester after the incident went unpunishedEngland captain Owen Farrell is set to be available for their Six Nations opener with Scotland despite a four-week ban for a dangerous tackle.
His ban will be reduced to three weeks if he completes the World Rugby coaching intervention programme.
That would allow him to be picked by new England boss Steve Borthwick to face Scotland on 4 February.
Farrell was cited after making contact with Gloucester forward Jack Clement's head with his shoulder on Friday.
The 31-year-old will definitely miss Saracens' European games with Lyon and Edinburgh and the Premiership trip to Bristol.
Provided he completes the necessary intervention programme the final week of his ban will be disregarded.
It gives some relief to new England head coach Steve Borthwick, with fly-halves Marcus Smith and George Ford both out injured.
The offence - which Farrell admitted to - was deemed to be at the mid-range of dangerous tackles and attracted a six-week ban as a starting point.
He was given two weeks' mitigation for his early admission of the charge and "exemplary" conduct during the hearing.
"The panel accepts that the player thought he had struck the chest of his opponent but in our view the footage confirms he was wrong," Farrell's disciplinary report said.
"We acknowledge there was no injury to the opposition player and have taken this into account in our decision.
"We do not however think that this effects our conclusion that a high degree of danger existed."
It is the second time in less than two-and-a-half years that Farrell has been banned for a dangerous tackle.
In September 2020 he was suspended for five weeks after a dangerous tackle on Charlie Atkinson in a game against Wasps - the offence was deemed to be at the high end of severity and had a 10-week ban as its starting point.
'Not as simple as it sounds' - Analysis

A three-game ban sounds simple - sadly it's not. The judgement read that the games have to be "meaningful" and the third game on that list for his club side Saracens is one that he wouldn't necessarily play in anyway.
If the 101-times capped fly-half is named in new head coach Borthwick's England squad on Monday, normally most England players are rested the weekend before the Six Nations - unless released back to their clubs for game time. If Farrell was to be released back to Saracens he wouldn't be able to play in their game against Bristol anyway.
Therefore, if he's named in the England squad, it will now come down to the RFU disciplinary panel to decide if the all-important third "meaningful" game will be for his club or country.
