JACKSONVILLE, Fla. -- At first glance, the brace on Sen'Derrick Marks' right knee appeared to have a gold and black design that looks a lot like the fur that is pictured in the Jacksonville Jaguars' logo.

Which made sense. You can get casts for broken bones in team colors and logos. You can get a casket emblazoned with a college logo, too. So an NFL-themed knee brace is logical.

Except upon closer inspection, Mark's brace turned out to have a snakeskin design. A bit disappointing, but still stylish.

What isn't disappointing is the progress Marks has made in his recovery from a torn ACL. The 6-foot-2, 294-pound defensive tackle is right on track in his rehabilitation and should be able to return to the field early in the 2015 season.

"It’s been progressing pretty well,” Marks said. “It’s getting better and better every day. I’m going along with the flow, and however it comes about I’m just doing all the work I can. As far as the protocol and what’s on paper, I’m right on schedule of where I’m supposed to be. All that’s great.

“I don’t know exactly when the return date is supposed to be. “[Jaguars team physician Kevin Kaplan] hasn’t set a date and I really don’t want to hear a date. I just want to continue to work and get it stronger as every day goes along. I’ll just see how it is when that date toward the season comes."

Marks had surgery in early January and has spent the past several months in Jacksonville rehabbing alongside defensive tackle Roy Miller, who had surgery to repair torn cartilage in his knee in January. Marks won't participate in any of the upcoming OTAs and minicamp, and it's likely he won't do much -- if anything -- during training camp. It is possible for him to be cleared to play in the season opener because that would be roughly nine months after his surgery, which is now generally accepted as the shortest recovery time with ACLs.

It took 10 months for rookie cornerback Aaron Colvin to make his return to the field last season. He suffered a torn ACL during Senior Bowl practices in late January 2014 and made his NFL debut in Week 12 against Indianapolis on Nov. 23.

There hasn't been a specific date set for Marks' return but he's hoping Sept. 13, which is the day the Jaguars open the season at home against Carolina.

"That would be my target, but other than that, I’m not pushing it," he said.

Marks, who is entering his seventh season, led the Jaguars with 8.5 sacks in 2014 and he has 12.5 of his 15.5 career sacks in his two seasons with the Jaguars. He signed a one-year contract as a free agent in 2013 and played so well that GM David Caldwell rewarded him with a four-year, $22 million contract through 2017.
