49ers not excited to face Walker

SANTA CLARA, Calif. – The San Francisco 49ers will face one of their former offensive weapons Sunday in Tennessee.

All-purpose tight end Delanie Walker left the 49ers for the Tennessee Titans in the offseason as a free agency. He has given the Titans’ offense a similar spark as he did the 49ers. San Francisco coach Jim Harbaugh has noticed is not excited about playing against him.

“I’m not happy to see him in a Titans 82 jersey,” Harbaugh said. “He’s really playing well. On a personal level, I miss Delanie. Wish him a long and successful career and have great memories of him when we were teammates. But, I know the competitor he is. I know the player he is. Our challenge, our task in defending him is high.”

In other 49ers’ notes:

  • Titans coach Mike Munchak -- a Hall of Fame offensive lineman -- lauded the recent play of the 49ers’ offensive line. Quarterback Colin Kaepernick said his appreciation for his teammates goes beyond the line of scrimmage. “I think my appreciation for them isn’t just for what they do on game day,” Kaepernick said. “They come in every day. They work their butt off. They’re in there lifting early in the morning. Practice, they’re running around making sure they’re putting in work. So, the end result that comes out on game day is because of the hard work they put in.”

  • Rookie pass-rusher Corey Lemonier has been playing extensively the past three games with Aldon Smith receiving treatment for substance abuse. Lemonier had his best game Sunday against Arizona when he had a sack for a safety and forced a fumble. He said he is not thinking as much as he was earlier in the season and it is helping his game.
