JACKSONVILLE – Gus Bradley summed up the Monday mood quickly.

"Still painful, watching that tape," he said.

Those were the Jaguars' head coach's first words to the media Monday, a day after a loss to the Tampa Bay Buccaneers at Raymond James Stadium in Tampa.

As of Monday afternoon, the Jaguars had another concern.

This one's at the quarterback position, where starter Blake Bortles sustained a Grade 1 AC Joint sprain in his right throwing shoulder early in the 38-31 loss to the Buccaneers.

Bortles played through the injury, throwing for a career-high four touchdowns. The Jaguars announced that he is experiencing soreness and that his status will be updated throughout the week.

Bradley said Bortles could miss practice Wednesday.

"Don't be surprised if you don't see him out there Wednesday, but don't be alarmed by that," Bradley said, adding that it was unclear exactly when Bortles sustained the injury. "If he could practice on Wednesday, it would be a situation where we don't want him to be sore and affect his throwing mechanics. I would anticipate that.

"We'll see, but we think he should be OK…. Right now, we think he should be in good shape."

Mostly on Monday, Bradley discussed many of the same issues he discussed Sunday afternoon following the loss. He was animated, candid and pointed following the game, and he continued in that vein during his next-day news conference at EverBank Field Monday.

Bradley discussed extensively the continued mistakes made by the Jaguars in recent weeks, and addressed the issue of accountability. He was asked if changes could become necessary if mistakes continue.

"You trust people until they prove unreliable," Bradley said. "If they're unreliable, then you have to make changes … I agree 100 percent. Some positons, we have to take a look at and we have to weigh this out. The NFL is Tolerate Until You Can Replace, and that's for all of us. That's for all of us.

"That's the environment we know that we're in. The players know we're in that environment, and the coaches. That's just a fact of life. The players need to sense that."

Bradley said he planned no coaching staff changes this week, or any changes in coaching responsibilities. When asked about possible changes in personnel, he said the staff had not met in detail regarding that issue. He also said he hasn't discussed personnel changes with General Manager David Caldwell.

"I think I can be stronger on the practice field," Bradley said. "I think the players need to feel me, that when a situation occurs, to hear my voice – offense, defense and special teams. I don't think I've been as animated on the field when it comes to those issues, so I think you'll see that part change."

Bradley had said on Sunday while the team felt prepared entering the game perhaps it wasn't as prepared as necessary. He addressed that again Monday.

"It sure felt like it (that the team was prepared), but we didn't react that way," Bradley said. "I'll give you the tone of the (Monday team) meeting: 'We each (offense, defense, special teams) took turns – and I'm talking about coaches included – making mistakes.' … So, you end up with 25, 30 mistakes – whatever the count is.

"You look at it and you go, 'How can we get this fixed? How can we get all these mistakes fixed?' I think the biggest message to our team is, 'Personal responsibility.' … They each need to take personal responsibility and get their one mistake, two mistakes, corrected so we can see this get taken care of. That's the issue we're dealing with right now."

Also around the Jaguars:

*Running back Bernard Pierce, who missed the second half with a hamstring injury, also reported concussion symptoms following the game. He is in the NFL's concussion program. Pierce also on Sunday had an usual play on which he blocked a Buccaneers defender when covering a punt, something that Bradley said could have been related to the concussion.

*Running back T.J. Yeldon sustained a groin injury in the fourth quarter Sunday and did not return. His status is expected to be updated later in the week.

*Other injuries to be updated throughout the week: cornerback Davon House (hip contusion sustained Sunday), middle linebacker Paul Posluszny (missed Sunday's game with a high-ankle sprain), wide receiver Marqise Lee (missed the last two games with a hamstring injury), defensive tackle Sen'Derrick Marks (out preseason and regular season with a knee injury), running back Denard Robinson (missed the last three games with a knee injury), safety James Sample (missed Sunday with a shoulder injury) and tight end Julius Thomas (played Sunday after missing first four regular-season games with a hand injury). …
