Marcus Peters was fined by the NFL and suspended by the Chiefs this week after tossing a penalty flag into the stands during the fourth quarter of last Sunday's loss to the Jets.
Chiefs coach Andy Reid said Wednesday the Pro Bowl cornerback would not play in Sunday's game against the Raiders. But there is apparently more to his suspension than tossing a flag into the stands at MetLife Stadium and leaving the field.
NFL Media reported Saturday that Peters got into an argument with a coach on the way to the airport following the game.
Reid said Peters tossing the flag into the stands "was the wrong thing to do" but suspending him was for his unsportsmanlike conduct that followed.
"I made it off of the thing that happened on Sunday," Reid said Wednesday. "That was it."
Peters, a two-time Pro Bowler, was fined $24,309 for the toss and admitted to NFL Network's Michael Robinson he behaved poorly later in the 38-31 loss.
"I spoke to him this week, very much apologetic," Robinson said Saturday during "Good Morning Football Weekend." "He hates the way this thing came out.

"I think the loss of Eric Berry has done some damage to Marcus Peters on a personal note, just not being able to have that guy like an Ike Taylor in that locker room to be able to lean on when you're going through something."
