Polian addressed Manning's throwing session during a Tuesday interview with SiriusXM radio.
"He can throw the ball with good velocity for about 30 to 35 throws in a limited area, 25-30 yards," Polian said. "That's a lot better, almost 100 percent better, than he was in September, before he underwent the surgery.
"Can I tell you where he's going to be two or three months from now? No, I can't and I'm not sure anyone can. All I can tell you is the arrow is up and he is improving in virtually every measure."
