initial roster for 2016, needing to shave 23 players off the team that played the Broncos Thursday night (because they acquired cornerback Marcus Cooper in trade with the Chiefs Friday).

Among the notable names released including quarterback Matt Barkley – the Cardinals will go with two quarterbacks on the active roster – defensive tackle Red Bryant and safety Chris Clemons.

Among the "surprise" players to make the 53 thus far include undrafted rookie linebacker Lamar Louis and defensive tackle Olsen Pierre. Pierre sticking around means the Cardinals kept nine defensive linemen.

The full list of cuts:

QB Matt Barkley

C Taylor Boggs

CB Cariel Brooks

DT Red Bryant

WR Marquis Bundy

LB Donald Butler

S Chris Clemons

T Rob Crisp

S Matthias Farley

WR Brittan Golden

CB Trevon Hartfield

WR Chris Hubert

G Antoine McClain

CB Harlan Miller

TE Ifeanyi Momah

RB Elijhaa Penny

T Given Price

LB Shaq Riddick

WR Jaxon Shipley

TE Hakeem Valles

RB Kerwynn Williams

CB Ronald Zamort

The Cardinals also waived-injured LB Tristan Okpalaugo (knee).

Claims on the waiver wire begin Sunday, and practice squad creation will last through the weekend. Among the possibilities to bring back to the Cards' practice squad – assuming they are not claimed elsewhere – are Barkley, McClain, Hubert, Miller, Penny, Shipley, Zamort, Riddick and Momah.

Arians said he isn't personally involved in every cut, but if a veteran he knows well is going to be released, the coach said he is the one who delivers the news.

"That's the hardest part of this business," Arians said.
