The Cardinals game on Oct. 27th will be 39 days post-surgery (about 5 1/2 weeks). Then the bye, then the Falcons come to the Dome on Nov. 20th, 53 days after the surgery (7 1/2 weeks).
Lots of unknowns regarding Brees' rehab and getting-back-in-the-groove practice work to come. Coming back against the Cardinals would be a gigantic deal, IMHO.
