Kerry Collins is expected to start for the Titans on Sunday against the Jaguars. Collins is probable with a calf injury. Titans rookie quarterback Rusty Smith made his first NFL start last week for Tennessee with Vince Young on injured reserve and Collins hurt. "Kerry was better today. We're encouraged. We'll see how he warms up," coach Jeff Fisher said. "He's gotten plenty of reps. We'll see how he feels. It's different getting ready to warm up and practicing than it is getting ready to warm up and play a game. So we'll see how he is."
