Gilbert pleaded guilty to a tip tackle on the Waratahs loosie Michael Hooper.
Gilbert has been suspended from all forms of the game for 5 weeks, up to and including 25 June 2022.
The Foul Play Review Committee deemed the act of foul play merited a mid-range entry point of 10 weeks due to a combination of features including the degree of recklessness exhibited and the danger posed to the tackled player.
