JACKSONVILLE – Gus Bradley said there would be rotation in training camp early, and plenty of it.

Consider the Jaguars' Head Coach true to his word.

Some significant rotation Wednesday came on the interior of the offensive line, where veteran offensive lineman Jacques McClendon worked extensively with the first-team line at center, sharing time at the spot with veteran Mike Brewster.

"You saw us move some guys around," Bradley said Wednesday following the first practice in full pads at Jaguars 2014 Training Camp.

The team worked for a little more than two hours at the Florida Blue Health and Wellness Practice Fields, and as Bradley indicated before camp would be the case, there was extensive rotation in spots.

Starting running back Toby Gerhart, backup Jordan Todman and rookie Storm Johnson all worked with the first team in 11-on-11 drills Wednesday, and defensive end Tyson Alualu – primarily working with the second-team behind Red Bryant at the Jaguars' five-technique end position – started 11-on-11 drills working with the first team on the other side of the line.

"We talked (during) OTAs, about 'Hey it's great to evaluate now, but when we get into training camp and the full pads come on, it'll give us a better idea,'" Bradley said . "That's what today's the start of with the pads."

McClendon, who began training camp primarily rotating with Brandon Linder at right guard, worked exclusively at center Monday, then did so again Wednesday morning.

"Any time you're competing for a spot, you have to show the value you bring," McClendon said. "I want to make sure can bring some kind of value to this team, carve out a role and do whatever I can to help. I've got to be versatile. That's my key to the season, for me to show some versatility."

He also got some first-team repetitions at right guard Wednesday.

"Jacques got some reps in there at the center spot, just to see what the best combination is, or at least give him an opportunity to go in there and see what he does when he does get that opportunity," Bradley said. "But it's not just singled out to him. Other guys have gotten that opportunity, but that's one we're looking at."

The Jaguars' center position is uncertain entering training camp because of the retirement of veteran Brad Meester, who started every game there the past five seasons. Brewster, a third-year veteran from Ohio State, started 10 games at guard last season and worked at first-team center throughout the offseason.

"I talked to (interim offensive line coach) Luke (Butkus) and it's competition, and we also want to get (him) McClendon some reps," Brewster said. "If I went down, someone has to be ready.  It's either going to be him (or rookie center Luke) Bowanko. Someone has to be ready.

"I got to take some snaps with (rookie backup quarterback) Blake (Bortles) today, and that was good. We never take snaps together, so it's good to work with him. We're just doing everything we can to get the line ready for the season."

FRUSTRATION AT TIGHT END

Jaguars tight end Clay Harbor's focus now is on the regular-season opener.

For the next four weeks, that focus will be more mental than physical, with the fifth-year veteran expected to miss at least that much time after sustaining a calf strain Monday in the team's practice at Bartram Trail High School.

Harbor strained the calf running routes in a non-competitive drill against no defenders, and called it a "bad break."

"I've never pulled a muscle in my life," he said.

Harbor caught 24 passes for 292 yards and two touchdowns last season playing in the team's move – or "H-Back" – tight end position. He sustained an ankle injury in the regular-season finale, but entered training camp fully recovered and said Monday's injury was unrelated and to the ankle on the opposite leg.

"Right now, I'm focused on getting my body right," Harbor said. "September 7 is that first game of the year, and I'm trying to make sure everything I do is geared toward that and doing everything I possibly can to heal up quicker and get out there."

Harbor said he had never missed a training camp practice in four previous NFL seasons.

"I love being able to get out there and work everything out, and get everything in your game where you want it to be before the season starts," he said. "It's bad luck to not be able to do that. I just have to take a lot of mental reps and be a professional."

LOOKING ON . . .

*The Jaguars' rookie second-round wide receivers, Allen Robinson and Marqise Lee, continue to show up early in 2014 Training Camp. Bradley said of Lee on Wednesday, "He's freakish in his skill set. We hope it carries over." …

*Attendance for Jaguars 2014 Training Camp Day Five was 1,504, bringing the four-day total at the Florida Blue Practice Fields to 7,847. Attendance for the practice at Bartram Trail High School Monday was 3,329, meaning 11,176 have attended the first five days of training camp. …

BRADLEY SAYS

"(Running back Jordan Todman) is picking up more. You're seeing him break some. The other day he had one where he broke and you saw him accelerate. Today he had another one, and I think that's what we're counting on him for – to give that change-up, that burst that we know he has. I think the last couple of days we're seeing it."

SEXTON SAYS

A daily training camp thought from Jaguars.com Senior Correspondent Brian Sexton …

"Full pads used to create a huge buzz because they used to go live. There was a whole lot more live activity. People understand now how a practice is run and why coaches do things the way they do. The goal with this era of football is to get guys to the regular season healthy. If (Jaguars Head Coach) Gus (Bradley) wants in a period to go live, he can, but they still don't want leg shots and they're going to be cautious with the way they approach. I sound old for saying this, but I remember when there was a huge buzz about the first day in pads. Everybody lined up to see guys hit, but it's limited now because of the way the game is played. It's the right way to do it, but it's a way the game has changed in 20 years."

LAGS SAYS

A daily training camp thought from Jaguars Radio Analyst Jeff Lageman …

"When things aren't perfect are when (rookie quarterback Blake Bortles) is better. What's impressive about him is his ability to adjust and be athletic and throw on the run or adjust in the pocket. Nothing's ever perfect in the NFL. You can't teach what he does well. He has a ways to go, but the little things you see you like."
