Rams cornerback Trumaine Johnson left Sunday's game on a cart after suffering a significant ankle injury, believed to be a high ankle sprain. Reports today suggest that his fibula is not fractured, which is the other common result for the type of contact in which he was injured, so an MRI scan will likely determine the severity of the high ankle sprain. With Johnson leaving the game on crutches with a protective boot over his ankle, he is expected to miss time with the injury -- a Grade II sprain likely means a 2- to 4-week absence, whereas a Grade III sprain would typically rule Johnson out for around 6 to 8 weeks.
