WATFORD, United Kingdom – The task is as much mental as physical.

Doug Pederson said that's the reality when a team is struggling, and the Jaguars' third-year head coach emphasized that Monday.

These are tough times, and focus matters.

"We just have to make sure these guys stay mentally positive with each other, stay positive during the week," he said.

Pederson, speaking a day after the Jaguars' fifth loss in six games to start the season – 35-16 to the Chicago Bears at Tottenham Hotspur Stadium – reiterated what he said following the game.

That's that culture matters in difficult times.

"Obviously, we've lost some games here," he said. "We want to change that culture to a winning culture. That's why we coach and that's why we play. These guys bust their tails during the week, and even though we haven't won yet, I don't want them to feel sort of mentally defeated.

"That's where the slippery slope comes in. If you feel like you're going into a game where you don't have a chance, then you're not going to have a chance. You're not going to give yourself an opportunity to win that game.

"That's what I mean by that culture. Bottom line is just go out and have fun and play. It's a great game to coach and a great game to play. But winning obviously helps that."

The Jaguars, who led 3-0 after outgaining the Bears 98-7 In the first quarter, allowed Chicago to outgain them 216-13 in the second quarter with a 13-0 first-down advantage. Bears quarterback Caleb Williams threw four touchdown passes for the game, with Jaguars now having allowed 59 points in the last five quarters.

Sunday marked the third time in six games this season the Jaguars have allowed at least 34 points. They beat the Indianapolis Colts 37-34 in Week 5 and lost to the Buffalo Bills 47-10 in Week 3.

"We've got to make sure that, No. 1, as coaches, we prepare our players during the week," Pederson said. "We show them everything we can. What to anticipate on game day and making sure that they're prepared mentally, more so than physically."

Pederson also noted on Monday that cornerback Tyson Campbell may return Sunday against the New England Patriots after missing the last five games with a hamstring injury.

"That would be a big boost defensively there," Pederson said. "That would be a big boost defensively there. I think it would help the whole defense."

Two other key defensive contributors/starters, safety Andrew Wingard (knee) and linebacker Foyesade Oluokun (foot), remain on injured reserve and could begin the process of returning in the coming weeks.

"Foye is an emotional leader, as well as that inspirational guy and a good football player, and when you're missing those two starters like that (Campbell and Oluokun), it does impact your defense," Pederson said. "We've got to make sure, one, it starts with the coaches, and then two, if the players just take the lead from there."

Safety Tashaun Gipson Sr., signed as an unrestricted free agent this past offseason, served an NFL suspension the first six games of the regular season – and Pederson said the team is waiting this week for the league to clear him to play.

"Maybe that'll happen this week or in the near future," Pederson said. "These are veteran players who can bring that leadership back there in the secondary. "We're still learning, and again, it goes back to just making sure, as coaches, we prepare these guys, put them in the right situations, and then ultimately the communication on the field."

Pederson added, "I think there's some rotational things now that we can do. We're starting to get more bodies back, and that's a positive to the entire defense."

Pederson also on Monday addressed safety Andre Cisco saying following Sunday's game that he saw "a lot of quit" and that it felt "early in the game" that the team "wasn't playing as one."

Pederson noted that players were off Monday and scheduled to begin practicing and preparing on Tuesday to play the Patriots at Wembley Stadium in London Sunday.

"I haven't seen the players today, being the schedule is a little bit different," Pederson said. "I would like just to get some clarification from his (Cisco's) side. It's his observation, but I don't think it was necessarily meant to harm anything or point a finger at anybody or anything like that.

"When you get in a game like yesterday, that sometimes is the feeling. We've been on the other side of that, too, where we've had games where we felt like we've had that type of success, and you feel that way with your opponent.

"I don't think it was necessarily a finger-pointing."
