JACKSONVILLE – The heat came in hard, and the Jaguars put in extended work.

The Jaguars continued their third full week of training camp with a two-hour, 40-minute practice at the Dream Finders Homes Practice Complex adjacent to TIAA Bank Field Sunday afternoon, working in difficult 90-degree temperatures on Day 13.

They are scheduled to play host to the Philadelphia Eagles in a Preseason Week 2 games at TIAA Bank Field Thursday at 7 p.m.

The Jaguars worked extensively on red-zone drills Sunday, and also had a two-minute session, one-on-one pass rush and extensive 11-on-11 work.

Jaguars Head Coach Doug Marrone, after speaking to the media Saturday afternoon before practice, did not speak to the media Sunday. He is scheduled to hold a media availability before the Jaguars' 8:45 a.m. practice Monday.

Also Sunday: The Jaguars signed rookie offensive lineman Ka'John Armstrong, ninth-year offensive lineman Ben Ijalana and first-year tight end Ethan Wolf. TTe Jaguars waived offensive lineman Jordan Agasiva and offensive lineman Andrew Lauderdale, and released running back Benny Cunningham via injury settlement. The Jaguars now have 90 players on their active roster.

Here's a look at Day 13 practice:

PLAY OF THE DAY

There perhaps wasn't a clear choice for Day 13's standout play, but a few players continued to standout. Foremost among that group was safety C.J. Reavis, a first-year veteran who drew praise from Marrone following a 29-0 loss to the Baltimore Ravens in Thursday's preseason opener. Reavis on Sunday defensed pass in a late-practice red-zone drill then two plays later intercepted pass in the end zone from reserve quarterback Alex McGough.

* INJURY WATCH*

Wide receiver Marqise Lee and left tackle Cam Robinson remain on the Physically Unable to Perform list; Lee missed last season with a preseason knee injury that included a torn anterior cruciate ligament while Robinson missed the last 14 games of the season with a torn ACL. Linebacker Jake Ryan (knee) remains on the Reserve/Non-Football injury list. Marrone said Saturday it's uncertain if Lee and Robinson will be ready for Week 1 against Kansas City on September 8, and said Ryan also is a ways from returning.

Cornerback A.J. Bouye (hamstring) worked more extensively with the starters Saturday as he continues to return to full participation, while the following players remained out of practice: Lee, Robinson, Ryan, wide receiver Terrelle Pryor, running back Ryquell Armstead, safety Cody Davis, linebacker Quincy Williams, guard Andrew Norwell (worked on the side), right tackle Jawaan Taylor (worked on side), tight end Ben Koyack, tight end Charles Jones, tight end Geoff Swaim and tight end Josh Oliver.

Cornerback Jalen Ramsey returned to practice after missing Saturday for personal reasons, and wide receiver Dede Westbrook was held out with groin soreness.
* THEY SAID IT*

SiriusXM Radio NFL Insider Adam Caplan attended practice Sunday. Caplan on the Jaguars entering 2019: "There are a lot of question marks. I don't think we know enough about this team yet. There's plenty of upside. With the improved quarterback play [of starting quarterback Nick Foles], that will certainly help the defense. But there's so much we don't know because of the injuries. The offensive line concerns me with the injuries. When you're left tackle is not there, for a right-handed quarterback that's a problem. I think they're the fourth team in the AFC South. That doesn't mean they're bad, though. I think they're around a .500 team – somewhere between 7-9 and 9-7. A lot plays into that."
