Worcester prop Val Rapava Ruskin has been suspended for six weeks by the RFU after pleading guilty to "acts contrary to good sportsmanship".
The 24-year-old pushed match official Greg Garner in the back with both hands during the first half of his side's Aviva Premiership 16-14 loss to Newcastle on Friday and was subsequently charged.
After a hearing in Bristol on Wednesday, the RFU's disciplinary panel said: "The panel heard from the player and, after carefully considering all of the available evidence, found that this was at the lower end of seriousness for this type of offending.
"The panel imposed a sanction of six weeks, which reflects the seriousness of making contact with a referee or any match official."
Rapava Ruskin will be unavailable to play until Sep. 4.
