Saints strong safety Kenny Vaccaro, who went through the full week of practice leading up to Sunday’s preseason game against the Texans, is not in uniform in the pregame.

The rest of the list of Saints who don’t appear to be available is no surprise. Cornerback Brandon Browner and linebacker Ramon Humber remain out, although they’ve been in uniform and practice in the past week.

The rest of the list — C.J. Spiller, Khiry Robinson, P.J. Williams, Ronald Powell, Dannell Ellerbe, Nick Toon and Anthony Spencer — did not practice this week at all.

Veteran safety Jairus Byrd remains on the physically unable to perform list. Byrd will not be available until he comes off the PUP.
