JACKSONVILLE -

It's too early to tell who will start at quarterback for the Jaguars this season, but the competition is compelling.

Blaine Gabbert and Chad Henne are both out to prove they deserve to be the main guy when the Jaguars take the field against Kansas City in the season opener on September 8. Gabbert struggled mightily in Saturday's practice, but rebounded on Sunday.

"I think that he just said, 'I gotta come back. It's another day. Let's go to work,'" said head coach Gus Bradley. "I really think his mind is trained to take responsibility. But to come back and demonstrate like he did, I'm excited about that."

Gabbert's top wide receiver, Cecil Shorts, says today's performance is what he expected from his quarterback.

"I feel like Blaine is always trying to prove something every day," said Shorts. "He's always got a little fire in his belly. He was slinging that thing today."

Chad Henne found success for a second straight day in 11 on 11 drills. But his mindset is to stay consistent.

"I don't know if we're worried about the results," Henne said after Saturday's practice. "It's just about going out there and competing each and every day and trying to get better."

Sunday's practice marked the first time the Jaguars wore pads in training camp. Maurice Jones-Drew, Brad Meester and Jason Babin were among the notable players who did not participate.
