Two important Saints starters didn't participate in practice on Thursday.
Safety/cornerback Kenny Vaccaro and left tackle Terron Armstead were sidelined with injury.
Armstead is nursing a hurt shoulder. Vaccaro has a groin injury.
Vaccaro was a first-round pick in 2013 and strictly played the safety position for the first four seasons of his NFL career. He's actually primarily played cornerback for New Orleans this year — and an unusual move for a veteran safety.
He currently has an overall PFF grade of +3.6 — the same as Bills cornerback E.J. Gaines — which is the 38th best grade among 115 qualifiers at his position.
Vaccaro has surrendered a passer rating of 40.7 on throws into his target area in 2017, the third-best among all qualifying cornerbacks.
As for Armstead, he's one of the game's best young left tackles.
He has a current overall PFF grade of -0.6, which places him in the No. 28 spot among 75 qualifying offensive tackles in the NFL. Armstead has surrendered six quarterback pressures (two sacks, four hurries) on 109 pass-blocking snaps so far, which equates to the 25th-best Pass-Blocking Efficiency among qualifiers at the offensive tackle spot.
Also on Thursday, Saints No. 1 wideout Michael Thomas was limited with an ankle injury. Starting defensive end Alex Okafor was also a limited participant with an ankle injury. Starting right guard Larry Warford was limited with an abdomen injury.
