JACKSONVILLE – Calais Campbell knows the rules, and one rule is clear:
You don't panic during adversity.
Another rule: good NFL teams don't lose two consecutive games – and the Jaguars' veteran defensive end and defensive co-captain discussed the second rule Monday.
"Throughout the season, to be a good team, you can't lose two in a row," Campbell said Monday, a day after the Jaguars' 30-14 loss to the Kansas City Chiefs at Arrowhead Stadium in Kansas City, Missouri.
"It happens. You see it here and there. Good teams can still find a way to scrap in there and make it to the playoffs, but the real good teams consistently don't lose two in a row. It's just the way it's always been. You have to bounce back and be consistent. It's an against-the-wall mentality."
The Jaguars' difficulties Sunday extended beyond allowing the Chiefs five scoring drives and 424 yards offense.
Corey Grant, the Jaguars' third-team running back and a key big-play threat, sustained a season-ending foot injury and will be placed on injured reserve. Tight end Austin Seferian-Jenkins also will be placed on injured reserve with a core muscle injury, and left tackle Josh Wells left Sunday's game in the first half with a groin injury.
Wells had been playing in place of starting left tackle Cam Robinson, who sustained a season-ending torn anterior cruciate ligament in Week 2. Josh Walker finished the game Sunday playing for Wells, who said Monday he was unsure the extent of his injury.
Head Coach Doug Marrone said Monday he expects Wells' status to be week to week.
"We try to build a good enough team with depth that the next man steps up and he has a role, responsibility," Campbell said. "He does it to the best of his ability and we just keep chugging forward. You can't panic. You can't hit the reset button. You just keep playing football.
"You've got to be consistent. I don't think we have to do anything different. We're going to just prepare the same way we always prepare. In this business, guys go down. That's part of the game. It sucks, but it's next man up."
Also:
*The Jaguars' offense allowed 11 hurries and five sacks Sunday after having allowed 16 hurries and six sacks over the first four games. Even before Wells' injury, the offensive line was dealing with injuries with center Brandon Linder (back), left guard Andrew Norwell (foot), right tackle Jermey Parnell (knee) and right guard A.J. Cann (triceps) missing a practice or practicing limited last week. "We just have to trust in each other," Wells said Monday. "The expectation level is still going to stay high. It's about putting your head back down, going back to work and continuing to grow. There's still a lot of the season left. Week to week, we have to come out and try to get a win." …
*A highlight Sunday: the play of rookie wide receiver DJ Chark Jr., who caught two passes for 68 yards in the first half. Chark, who entered the game with two receptions for 19 yards in four games, caught a 38-yard pass in the first quarter and a 30-yarder in the second quarter. "Knowing you can do it is one thing; actually doing it is another," the second-round selection from Louisiana State University said Monday. "I knew I could do it. Everybody on the team knew I could do it. We were just waiting on it to happen. Some things you can't wait on. You have to go take it, so I just continued to work." …
