"You'll see on Saturday," McCoy said.
The Chargers have been decimated by injuries this summer, and the sight of Rivers donning a baseball cap instead of a helmet during drills came with an unsettling feeling.
SAN DIEGO (AP) — San Diego quarterback Philip Rivers didn't practice on Wednesday.
Rivers, who was sacked an AFC-high 49 times last year, was pushed around with regularity in his short stint in Chicago and was sacked three times.
Chargers fans shouldn't hit the panic button. Rivers was just getting a veteran rest day from rookie coach Mike McCoy.
The third exhibition game is the one when starters usually play longer.
So if the Chargers' revamped offensive line is putting McCoy's quarterback in harm's way, maybe his playing time will be compromised.
"It wasn't that bad,Cheap Jerseys Free Shipping," Rivers said,Cheap NFL Jerseys, with a smile. "I'm still heavily involved as you can imagine."
"I don't want to say it's a half, it's this or that. I will have a gut feel on Saturday night of saying,Deion Sanders Falcons Jersey UK, 'Hey this is where I think we want to pull these players.'"
Rivers, the football equivalent of a gym rat, always loves to play. That's what made sitting out Wednesday so challenging. But giving way to backup Charlie Whitehurst has some benefits.
McCoy won't say if defensive end Corey Liuget will play Saturday night. He was pulled from last week's game with a shoulder injury.

"My arm has felt good all camp, but it was probably good to take a day off of throwing," Rivers said. "And I know it's good for Charlie to get in there and play with the guys he would be playing with if he gets in there. So it has a lot of positives."
"We will see how it is going Saturday night and we will go from there," McCoy said.
What's not as clear is how long Rivers will be under center. He played in just three series in last week's loss at Chicago,2018 World Cup Russia Jerseys.
"I will let you know Saturday," McCoy said. "You guys asked me a couple of times but it is more of a gut feel of how we are doing, how things are going, what's the situation of the game.
Rivers will lead the offense on Saturday night when the Chargers visit Arizona.
How active some of the Chargers' mending players will be is a mystery. But it's clear rookie linebacker Manti Te'o won't play as he remains in a walking boot and hasn't practiced since spraining his right foot in the preseason opener.
But wasn't it like his teammates got to go out to recess and he didn't?
"I guess it is good and it is tough for me — I hate watching,Cheap NFL Jerseys China," Rivers said. "But it was good. You usually get one or so every training camp. We kind of mapped out and picked this day. I fought it for as long as I could."
