13-10 overtime win vs. Tennessee, Polamalu suffered an injury. Right now, it is being called a grade 2 hair sprain.
"We are still waiting for some further test results from our team stylist," said Steelers head coach Mike Tomlin. "Once those tests are completed, we'll have a better idea about when Troy can return."
Despite the injury, Polamalu was surprisingly upbeat after the game.
"This isn't the first time I've sprained my hair," said Polamalu. "With a mane like this, it's bound to happen. It's just a risk of playing football. With the proper treatment, I'll be on the field again in no time."
Polamalu's rehab regiment is said to include shampooing with Head and Shoulders three times a day, and drinking vast amounts of Coke and Coke Zero.
