Titans’ quarterback situation remains unclear

Jake Locker’s struggles in his first preseason start have the Tennessee Titans pushing back their timetable for announcing their starting quarterback for this season.

Mike Munchak had pegged the third preseason game for making that decision, but neither veteran Matt Hasselbeck and Locker have been impressive splitting starts through the first two exhibitions. Munchak hadn’t met with his assistant coaches following a 30-7 win over Tampa on Friday night, so he’s not ready to announce his starter for Thursday night against Arizona yet, either.

“We have two more weeks to see plenty, so we’ll make our announcements when we feel the time is right,” Munchak said.

That’s different from when Munchak said he didn’t want to pick his starting quarterback the week of the season opener Sept. 9 against New England.

But Munchak says both need more work.

“Overall, we’re just not moving the ball as effectively as we need to,” Munchak said.

Chamberlain out

New Orleans Saints reserve linebacker Chris Chamberlain says he is out for the season after injuring his left knee Friday in an exhibition game against the Jacksonville Jaguars.

Chamberlain confirms in postings on his Twitter page that MRI results show he has torn his anterior cruciate ligament.

Brown sidelined

Arizona Cardinals starting left tackle Levi Brown has a torn right triceps and probably will not play this season.

Coach Ken Whisenhunt revealed the extent of the injury at his news conference, saying Brown will require surgery, with an anticipated recovery time that would approach the end of the season.
