Some good news from Indy Star's Phil Richards:
Charlie Johnson was moving slowly and making no predictions Monday, but he had some good news: A magnetic resonance imaging test on his left knee indicated no serious damage.
Very good news to hear that no damage was done. However, this injury does provide some intrigue. If C.J. cannot play Sunday night against the Tennessee Titans, it is likely that the Colts will turn to Tony Ugoh, who was benched back in August in favor of C.J.
