Barrington's red revoked
The charge for dangerous charging, contrary to law 10.4(g) was dismissed and he is free to play again with immediate effect.
Barrington was sent off by referee Ian Tempest for making contact with the head of Geoff Parling.
"Following very careful analysis, the panel found that Mr Barrington had not committed the act of foul play alleged. The incident arose out of the specific dynamic of Mr Parling falling unconscious into what would have otherwise been a legitimate contact by Mr Barrington," the RFU Disciplinary panel said.
However, Barrington's teammate, Brad Barritt was handed a three week suspension after pleading guilty to the charge of dangerous tackling, contrary to law 10.4(e).
Barritt tackled Geoff Parling dangerously, making contact with his head and escaped an on-field sanction but was subsequently cited by the citing commissioner.
"In line with the new sanctions a mid-range entry of six weeks was imposed on Mr Barritt reduced to three weeks in light of mitigation including his guilty plea," the panel added.
The RFU Disciplinary panel comprised of Jeremy Summers (Chairman) with Tom Rees and Dr Julian Morris.
