However, all signs pointed that way Friday.
"Kerry was better today. We're encouraged. We'll see how he warms up," Fisher said Friday. "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."
Collins sounded optimistic about his chances of starting Sunday and said the calf is feeling better.
"I'm feeling good," he said. "I've been able to kind of continue to do more and more every day ... So, hopefully, Sunday will work out so I can play. I'm getting real close."
The defensive line also is a concern for the Titans, with five of the eight players there listed on the injury report.
Defensive tackle Sen'Derrick Marks (ankle) is doubtful, and defensive tackle Tony Brown (knee) is questionable. Neither practiced Friday.
