JACKSONVILLE – The past is irrelevant.

Head Coach Doug Marrone has been consistent in that message when it comes to the 2018 Jaguars, and he stayed that way Wednesday morning when discussing the concept of resiliency.

"We have to establish that now," Marrone said.

Here's why Marrone discussed resiliency during his weekly Wednesday media briefing:

When the Jaguars (2-1) play the New York Jets (1-2) at TIAA Bank Field Sunday at 1 p.m., they will be one week removed from their first loss of the season: 9-6 to the Tennessee Titans.

The Jaguars are 7-1 under Marrone in games following a loss. Perhaps most notably, they went 4-0 in their first four such games last season – and that ability to respond after a loss was key to their first AFC South title and their first division title in 18 seasons.

The Jaguars not only won following a loss early last season, they won big in that situation – beating Baltimore 44-7, Pittsburgh 30-9, Indianapolis 27-0 and Indianapolis 30-10.

Marrone said one key to doing that is to study and correct mistakes from the previous loss, which he said the Jaguars did on what he called a "productive" Monday. Another key is practicing well throughout the week with a focused mindset.

Marrone added that while doing those two things matters, it's not enough.

"You've got to put in the work, got to put in the preparation, but you can't make the mistake of not understanding that it's a performance-based business," he said. "You have to do it on Sunday. Even if you go during the week and do a great job, when that Sunday comes you have to be able to put that on the field and be able to perform.

"That's how you get labeled – by your performance. Not by how you practice or by how you work. All that's doing is giving you hopefully confidence and preparation knowing you can go into the game and play at your top level."

Also:

*Starting running back Leonard Fournette (hamstring) is expected to practice Wednesday while backup running back T.J. Yeldon (ankle) is not expected to practice. Fournette has missed the last two games after sustaining the hamstring injury in Week 1 against the New York Giants; he missed practice the entire week leading to the Jaguars' Week 2 victory over New England, then practiced limited all three days last week. Yeldon played through an ankle issue the last two games, rushing for 58 yards on 10 carries against New England and 44 yards on seven carries against Tennessee. Yeldon aggravated the injury and was unavailable temporarily against Tennessee. …

*Also not expected to practice Wednesday for the Jaguars: cornerback D.J. Hayden (toe) and center Brandon Linder (knee). Linder is expected to miss Wednesdays routinely during the season to rest the knee while Hayden sustained a sprained toe last Friday. Tyler Patmon played the nickel in Hayden's place against Tennessee. "We're trying to be as aggressive as possible in the treatment for him," Marrone said of Hayden.

*The following Jaguars players are expected to practice with injuries Wednesday: Fournette, right guard A.J. Cann (triceps), right tackle Jermey Parnell (knee), defensive end Calais Campbell (ankle) and tight end Austin Seferian-Jenkins (core muscle). Cann worked limited last week before missing the Titans game, while Parnell and Seferian-Jenkins have started all three games this season while practicing limited during the week. Campbell played through the injury Sunday and finished the game. …
