Titans to start off without Delanie Walker

NASHVILLE, Tenn. -- On an OTA day when tight end Delanie Walker was sitting out with a troublesome knee, I chatted with a high-ranking Titans person.

The defense won the day, but it wasn’t representative of where the offense stood, he said. And the offense is a lot different with Walker on the field.

We won’t see that offense for some time, now.

Walker had a knee scope a few weeks ago, largely to avoid the potential for any lingering issues.

Now he is on the physically unable to perform list as the Titans prepare for their first practice Thursday and coach Mike Munchak said the new tight end is likely to miss a couple weeks.

"Delanie missed three or four practices in the middle [of the offseason] with his knee being a little sore," Munchak said. "He finished with practicing in minicamp, actually looked good. We left here, we knew he had some soreness. I thought the time off would help him. It did, but he still didn't feel quite good enough."

The hope is he'll add a nice boost when he does return, and Munchak said it's a certainty that Walker will appear in preseason action.

“He’s a game-changer,” quarterback Jake Locker said. “He creates matchups for you inside and outside. He allows you to do some different things. He’s got a place. He’s explosive and dynamic, that’s not going to go away.”

Receiver Kevin Walter, who had back surgery, is expected to miss more time than Walker, a development that will help Marc Mariani get a maximum chance to make his case for a roster spot.
