NASHVILLE, Tenn. – Defensive lineman Karl Klug once again has a spring in his step, and that's good news for the Titans.

Klug, who suffered a torn Achilles last December, impressed everyone with his speedy recovery, and his dogged approach in rehab during the offseason.

And while Klug made it back in time for the season opener, he admits he didn't start feeling like himself again until more recently.

"It was like 2-3 weeks ago honestly," Klug said. "I don't know what happened. One day I just came in and I always felt like I didn't have a spring in that one foot and then that one day it was like, bam, I felt the spring again. I was like, OK, that's kind of nice.

"So I was able to move more like I was used to and that was a really, really gratifying feeling."

Klug had his most productive game in Sunday's 23-20 win over the Ravens. He recorded a half-sack, along with two tackles. He was credited with a quarterback pressure while playing 35 of the team's 75 defensive snaps.

Coach Mike Mularkey called it Klug's best performance of the season.

On the season, Klug has 16 tackles and a half-sack in seven games.

"Obviously, he was very effective," Mularkey said of Klug's performance against the Ravens. "(He) made a big tackle on a run that if it had gotten by him, it would have been a big, explosive run. That's probably the best game he's played. We're going to kind of talk about that in the team meeting, about what it took him to overcome that injury and get back to where he's at already, play at the level he did. That's a huge credit to him."

Klug, a fifth round draft pick in 2011 who is in his seventh NFL season, said he's glad to do his part on an improving defense.

"I felt pretty good physically, and mentally too. I was finally able to stay on the field a little bit and make a few plays, so it felt good," he said. "When I didn't have a spring, I was kind of running flat-footed; I was a little limited I thought. But now it feels good.

"(As a defense) there's always room to improve, but defensively we're playing pretty good, stopping the run and forcing teams in obvious passing situations, which is what we want to do. So now we need to focus on finishing games better I guess."
