It started where he was trying to block a field goal where he burst running as fast as he could to the ball but unfortunately he fell in his right knee strangely. He was in pain on the field. He was beening walked to the locker room when he didn't return.
There wasn't a word on the severity of the injury, but there also wasn't one after. It looked as if he was very good with injury and nothing happened. It looked as if he was nice and calm leaving like it was nothing but a small paper cut.
But Tyrone Carter was playing as a back up for Polamalu in the second half.
Well lets see Troy Polamalu is one of the most famous people in the NFL with his amazing tackles and when he was at the Super Bowl. Whenever you go to the stadium of course they have Rothiliessburger jerseys on, but also Polamalu.
Polamalu is one of the best players also, whenever you see the ball fly into the cold air and the wide-reciever make the catch he runs and tackles him so hard that he fumbles. Then as he runs he jukes the tackle and runs on the side almost out of bounds. Its the 40 then the 30, 20, 10 BOOM! Touchdown people bursting up as if they are curious and yell "YAAAAAA!!!" everywhere.
Thats what happens when Troy Polamalu gets on the field without doing anything.
