Last week, Larry Fitzgerald noted that Bruce Arians doesn't like to use the word "grind" when it comes to training camp. The coach made it obvious why today.

"It's not a grind," Arians said. "How can it be a grind when it's one practice (a day) in air conditioning, and you stay in a five-star hotel. That ain't a grind. A grind is two practices (a day), three hours, both in pads, in a (expletive) dorm and camp is off somewhere in the middle of nowhere. That's a grind. Two bars, nowhere to go."

The significance of two bars?

"One for the players, one for the coaches," Arians quipped.

-- The Cards seem to have gotten good news on a pair of injuries. LB Alani Fua (knee) doesn't need surgery and, if you can call it good news, DT Corey Peters only has plantar fasciitis. That could still sideline him a little bit -- it's up in the air right now -- but at least he didn't injure again his Achilles, which was an immediate fear.

-- Arians updated some of the long-term injuries: S Tyrann Mathieu (knee) and DT Frostee Rucker (foot) are out "probably two weeks," DT Robert Nkemdiche (ankle), CB Justin Bethel (foot) and CB Elie Bouka (hamstring) are probably less than two.

-- WR Larry Fitzgerald will get his veterans day off today. He was supposed to be off Tuesday but worked because so many receivers were sitting because of injuries.

-- Earl Watford will play a lot of center the next few practices, Arians said, to get him game-ready. Arians said offensive coordinator Harold Goodwin calls Watford "Knife" -- as in Swiss Army, since Watford can play every position on the line. His versatility makes him a strong candidate to be one of the backup linemen active on game days.
