Then again, that could change any day.
"When you live day-to-day," Polamalu explained, "you can't talk years, you can't talk weeks, you can't talk months. If anybody knows me, they say ‘Troy can you be here next week?' And I say, ‘Oh, I don't know what's going to happen next week. You have to ask me then.' I just try to deal with the present."
So Polamalu was asked if he had worried about his future as an athlete on any one day during his most recent rehabilitation.
"Um, no," he said.
After injury-plagued 2009 and 2010 season, Polamalu played in all 17 games in 2011, but the 31-year-old injured his calf in the opener this season and missed the next two games.
He came back against the Philadelphia Eagles and promptly injured his calf in the first quarter and missed the next seven games, before returning last Sunday in Baltimore.
Against the Ravens, Polamalu played in 47 snaps (77 percent of team total) and made 2 tackles.
"I felt good," he said on Thursday. "I felt good all game."
Polamalu was asked if he was "on a pitch count," or had his playing time decreased as a method of easing him back into shape.
"I don't know if I was on a pitch count," he said. "I think it was a better game plan going into the last game than it was going into the Philadelphia game when I injured myself."
Polamalu explained that in the week leading up to the Baltimore game he "was limited in a way in terms of repetitions."
He wouldn't say if he thought he would've been injured had the Steelers taken the same cautious approach prior to the Philadelphia game, but did say "it was just a different muscle."
When asked to elaborate on the different muscles in the calf, Polamalu said, "I don't know. I already gave you too much."
Polamalu is known for not talking about his injuries, but in a recent blog entry at his Troy43.com website titled "Thoughts on coming back from injury, life, and recent events …" Polamalu wrote, "After being out for so long, God has reminded me of why football is so important in my life."
It's apparently a sign that the 10th-year pro still loves and enjoys playing the game in spite of the recent injury woes.
He was asked if he gained a new perspective while sitting out.
"I wouldn't say new perspective," he said, "but just kind of reinforced the perspective that maybe I didn't appreciate as much as I used to."
Someone then asked Troy why he didn't do "much Troy stuff" against the Ravens.
"I don't know what ‘Troy stuff' is," he said with a laugh. "I just played, If that stuff comes, it comes."
