Billy Volek returned to Nashville on Sunday night, but said it's "time for me to move on." The Chargers, Chiefs and Raiders are interested in trading for Volek, who requested to be released or traded after the Titans signed Kerry Collins. Volek is represented by agent Drew Rosenhaus. "I haven't talked to Drew yet," Volek said Sunday afternoon. "We kind of gave this thing a rest through the week. Now I just have to wait and see. I have to do what is best for my career. "Tennessee fans have been great for me, and now it is time for me to move on."
