Redskins head coach Mike Shanahan indicated that left tackle Trent Williams suffered a Grade 1 strain to his medial collateral ligament (MCL), a diagnosis that’s far more encouraging than what many believed it would be (namely, a season-ending ligament injury).
Grade 1 sprains/tears are defined as “an incomplete tear of the MCL. The tendon is still in continuity, and the symptoms are usually minimal.” Usually, the injury comes with pressure and discomfort in the affected area, but usually takes 1-2 weeks to fully heal.
Shanahan did say that “most people play” with a Grade 1 MCL injury, perhaps indicating that Williams would be back sooner rather than later, if he missed any time at all.
Regardless, the Redskins and Williams avoided what could have been a disastrous injury.
