It means Pulu's Mitre 10 Cup season is over, with Counties-Manukau out of premiership semifinal contention and just one regular season match remaining against Tasman on Saturday.
Pulu was red carded for a dangerous tackle on Manawatu's Jade Te Rure in the 75th minute of last week's match in Palmerston North, which Counties-Manukau won 29-24.
He faced a hearing before New Zealand Rugby judicial officer Nigel Hampton QC on Saturday.
