Per an official release from The University, Maalik Wayns suffered a sprained medial collateral ligament in his left knee and is day-to-day, which means he'll possibly miss the USF game.
What is the medial collateral ligament?
Well, the medial collateral ligament (MCL) is one of the four ligaments, [along with the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) and lateral collateral ligament (LCL),] that serve to stabilize the knee.
What does this diagnosis mean?
Unfortunately, very little. Even a semi-specific diagnosis like a sprained MCL leaves some latitude as to the seriousness of the sprain. The fact that they're using terms like "day to day" as a timetable suggests that all they know about the injury is that it's not a tear.
What's the treatment?
Anti-inflammatory drugs, a knee brace and physical therapy are the most likely paths. Only very serious injuries to the MCL which involve knee instability require surgery.
Long term: Excellent
Short term: Wait and see.
