Treviso have been dealt a blow ahead of Sunday's clash with Heineken Cup giants Toulouse as Manoa Vosawai and Simone Favaro were suspended.
Italian back-row internationals Vosawai and Favaro were both issued with bans by PRO12 disciplinary panels on Wednesday following incidents in the recent game against Glasgow.
Vosawai was handed a three-week suspension after receiving a red card for a dangerous tackle. He is sidelined up to and including January 27.
Favaro was cited for striking a Warrior with his knee and is out for two-weeks, ruling him out of the final two Heineken Cup Pool weekends.
