Brumbies superstar David Pocock will miss two crucial Super Rugby matches after pleading guilty to a neck grab.

The flanker on Tuesday accepted a three-week suspension for grasping Chiefs No.8 Michael Leitch at a maul late in his side's loss at GIO Stadium on Saturday.

But with the Brumbies having a bye this round, Pocock will only sit out clashes with the NSW Waratahs at Allianz Stadium on April 16 and the Crusaders the following Sunday at home.

Pocock went unpunished in the match but was cited by SANZAAR early on Sunday morning.
