JACKSONVILLE – Soggy fields forced a change in venue Thursday.

And while the Jaguars' practice locale moved across the St. Johns River, Head Coach Gus Bradley said little else changed for the team Thursday.

The statuses of injured players didn't change significantly.

And the focus remained on preparation for the Miami Dolphins, with the Jaguars' Thursday, two-hour, twenty-minute practice moving from the Florida Blue Health and Wellness Practice Fields to nearby Episcopal School of Jacksonville.

"A special thanks to Episcopal for letting us come out there and use their field," Bradley said upon returning to EverBank Field. "It worked out great for us."

Rains left about four inches of water on the team's practice fields Thursday morning, and Bradley said the decision to work at Episcopal was made early Thursday.

"We went out there about 8:15 with our grounds crew and took a look at it," Bradley said. "We were going to wait until the last possible minute to make a decision, but as we saw the fields and the condition they were in we decided to go over there."

Bradley added, "Everything's on schedule. We left about the same time it takes the players to walk out on the field so it worked out great."

Bradley called Thursday's work "really sharp," with practice emphasizing third down and preparation for the Dolphins, the Jaguars' opponent at EverBank Field Sunday at 4:05 p.m.

"I just thought it was a very clean practice," Bradley said.

The Jaguars on Thursday also released their second injury report of the week, with wide receiver Rashad Greene, cornerback Dwayne Gratz and defensive tackle Sen'Derrick Marks the significant changes.

Greene, who sustained a back contusion Sunday against Carolina, was upgraded from limited participation to full. He worked throughout team activities both Wednesday and Thursday, but worked on Thursday without the red, non-contact jersey he wore Wednesday.

Marks, who worked limited Wednesday, did not participate in practice Thursday. He is in the process of returning from January reconstructive knee surgery and his absence Thursday was considered scheduled.

"He went through individual drills and moved around pretty good," Bradley said of Marks. "He found out where some areas maybe where he was a little more deficient than others. Now, he'll attack that area. His overall strength – he's on the right track."

Gratz, who left practice Wednesday with an ankle injury, did not practice Thursday.

"I saw him today and he felt pretty good," Bradley said. "I think it was more of a scare for us when it took place on the field for him, but then we got the X-rays and things came back. He's had an ankle injury in the past, I think last year, and it didn't seem to swell up as bad. We'll see how quickly he recovers from it."

The Jaguars' injury report Wednesday reads as follows:

Safety Josh Evans (illness, full), Greene (back, full), Lee (hamstring, limited), tight end Julius Thomas (hand, limited), linebacker Thurston Armbrister (back, did not practice), Marks (knee, DNP), defensive end Andre Branch (knee, DNP), safety Johnathan Cyprien (finger/calf, DNP), running back Toby Gerhart (abdomen, DNP), Gratz (ankle/DNP), Joeckel (ankle, DNP).

Bradley said the game-day status of Joeckel and Cyprien will be determined later in the week. If Joeckel is out, Sam Young is expected to start at left tackle with Luke Bowanko the possible backup. Right tackle Jermey Parnell is also an option at left tackle if necessary.

"It would have to be an extreme case for that to take place," Bradley said of Parnell playing left tackle.

Thomas and Branch are not expected to play Sunday. Lee has been out since early in training camp, and his limited work the last two days marks his first practice work since his injury. Bradley said Wednesday Lee could play Sunday.
