Furious about what he had just seen during the Jaguars' 33-16 loss to Oakland, linebacker Paul Posluszny didn't wait for reporters to turn their recorders or cameras on before expressing his disgust late Sunday afternoon.

"Have you ever seen a mess like that before?" Posluszny asked. "Am I overreacting or …"

Posluszny was critical of teammates Malik Jackson and Jalen Ramsey, each of whom was ejected during a stunning fourth-quarter meltdown for a team that was trying for its third consecutive win, repeatedly stating the team must hold itself to a higher standard regardless of circumstances.

"I think it's terrible," Posluszny said when asked about his reaction to the team's lack of poise. "We need to act like professionals at all times, regardless of what happens. To have guys get thrown out, multiple penalties over and over again, that's not who we are and we can't tolerate that moving forward."

Posluszny was just getting warmed up.

"I've never seen anything like that before," he continued. "That's unacceptable on a lot of different levels. Fans don't want to see that, you guys don't want to see that and we don't want to be a part of it. Just from a higher standard of playing in the NFL, we can't have that."

Stinging words from Posluszny considering how respected the 10-year veteran is with the team.

But it was that kind of fourth quarter for the Jaguars.

The ugliness began when Jackson was flagged 15 yards for roughing Oakland quarterback Derek Carr early in the fourth quarter. Angry with the call, Jackson was hit with an unsportsmanlike penalty for verbally abusing officials.

Following an Oakland field goal four plays later, Jackson continued his tirade, was served another unsportsmanlike penalty and ejected from the game.

Jackson isn't the first player to be ejected under the new NFL rule dictating disqualification for two unsportsmanlike conduct penalties. New York Giants center Weston Richburg is believed to be the first; he was ejected against Washington in Week 3.

"He's a passionate player and got caught up in it," coach Gus Bradley said of Jackson. "The things that take place out there, you have to keep your poise and he knows it - he's the first to admit it."

Jackson wasn't around to admit fault - teammates said he left the stadium while the game was still going on.

Ramsey wasn't around when the locker room opened to the media. He was ejected with Raiders receiver Johnny Holton for fighting with 3:35 remaining in the fourth quarter.

Jackson didn't have a tackle in the game and registered one quarterback hit. Ramsey notched a pair of tackles.

"During the game, it's proven - we lost our poise," said Bradley, whose team was flagged 13 times for 122 yards. "We became frustrated that things didn't go exactly as we had planned and some things took place on the field. You need to keep your poise and keep your composure. It ended up affecting us."

The Jaguars (2-4) have a quick turnaround at play at Tennessee on Thursday night.

Posluszny said he wasn't sure what caused Jackson and Ramsey's outburst, but that it didn't matter. He vowed that he and other leaders on the team will not allow them to be distractions moving forward.

"We need to maintain our poise at all times, regardless of what happens or what someone else does," Posluszny said. "Doesn't matter. The teams and the outcome is much more important than any of our individual emotions. We need to take that into account with everything that we do."
