Tennessee Titans tight end Delanie Walker returned to practice on Friday and was cleared to play Sunday against the Atlanta Falcons.Walker missed the two previous days of practice due to a knee injury. He was a full participant on Friday.”I have great coaches, a great training staff,” Walker told reporters. “I felt good today, running around, so I am looking to play on Sunday.”Walker enters Sunday’s contest with 499 career receptions and is looking to become the sixth active tight end with 500 or more.”I didn’t even know that I was reaching that mark,” Walker said. “Our PR department let me know about it. At the end of the day, I don’t think about it because when you think about things like that you tend to mess up. I am just going to go about my day and play on Sunday and if I get the catch, I get the catch. If I don’t, I don’t.
