Peat played every snap in Sunday's win over the Philadelphia Eagles but committed four penalties. His holding penalty took a 46-yard Alvin Kamara touchdown reception off the board. Later in the drive, the Saints settled for a field goal.
Tackle Terron Armstead is also playing with a pectoral injury, so the Saints will walk into the NFC Championship Game with the entire left side of their offensive line dealing with serious injuries. It's unlikely either Armstead or Peat will be at full strength by Sunday's game against the Los Angeles Rams.
That, of course, could be a major problem for Drew Brees given the presence of Aaron Donald and Ndamukong Suh prepared to bull rush their way to the quarterback.
The Saints tend to get the ball out of Brees' hands quickly as is, but giving him any time for downfield routes to develop will likely present a problem.
