"He's day to day, and (we're) evaluating him throughout the week," said Fisher, who promised an injury report on Wednesday.
Pro Bowl center Kevin Mawae is considered day-to-day with a shoulder injury, Titans coach Jeff Fisher said.
Mawae, who earned his seventh Pro Bowl spot in his 15th season, hurt his right elbow on Dec. 21 and missed the regular-season finale in Indianapolis. He has not practiced since. Second-year lineman Leroy Harris started at center in the 23-0 loss to the Colts and has practiced at that spot.
"It's still questionable. We're day to day, and hopefully things progress to where I'll be able to play next week," Mawae said. "But again, we're day to day right now."
Haynesworth, meanwhile, worked through about half the session.
"I'll be hopefully full practice tomorrow," said Haynesworth, with his sweat shirt soaked from his shoulders almost down to his stomach.
"I'm just happy I get to practice and knock some of the rust off in practice. By doing that, I feel I can almost be back to where I was before I got hurt."
