Chargers coach Mike McCoy didn't sugarcoat this.

Johnnie Troutman was flagged for a penalty late in the fourth quarter Sunday. McCoy didn't like it. On Monday, he called the penalty "critical." He called the mistake "unacceptable."

Now, Troutman won't be in the starting lineup this Sunday.

Call it a coincidence.

The Chargers left guard has done a solid job filling in this season, starting the past nine games for an offensive line hard hit by injury. He is expected to be relieved against the Giants, as left tackle King Dunlap appears set to return from a neck injury that's forced him to miss the past three games.

This sorts a shuffled deck.

D.J. Fluker moves from left tackle to right tackle, Jeromey Clary goes from right tackle to right guard, and right guard Chad Rinehart reverts to left guard. Troutman assumes the reserve role at which he began the season.

The Chargers used this arrangement the first two games. Because of injuries, they haven't since.

"The way the season has gone," McCoy said, "you play the healthiest guys, the best five guys up front that we think give us the best opportunity to win. It’s good to have everybody out there (in practice). We’ll see how the week goes and go from there.”

Troutman learned from his starts this year.

Sunday's game included.

Less than five minutes remained in regulation when kicker Nick Novak converted a 48-yard field goal that brought San Diego to within one score, 20-13. The play ended. TVs cut away in slow motion for a commercial break.

That is when Bengals linebacker Vontaze Burfict pulled a fast one.

Troutman was about ready to walk to the sideline when Burfict walked past, smushing his right foot onto Troutman's right foot. Troutman reacted with a shove.

"Usually the second guy gets caught," Troutman said. "I was the second guy, so I got caught."

Fifteen yards for unsportsmanlike conduct.

The Chargers lost field position that could've proven useful if the defense made a stop on the ensuing drive. It didn't, but McCoy still used the incident to make a larger point.

"You have to be poised under pressure," McCoy said. "It's something that whether you get baited or not, it's unacceptable. That's what I told him instantly after the play happened. I'm sure you all saw that. After the game, talking to the team, it's something we can't accept. You don't want any unsportsmanlike conducts. ... That's kind of certain players' jobs to bait you into certain penalties. You have to stay away from it. It really hurt our football team."
