Puka Nacua knee injury: MRI scheduled, PCL sprain a concern

Puka Nacua injured his knee on the Rams' final offensive snap and is scheduled for an MRI Monday. The encouraging part: the Rams reportedly do not believe he tore his ACL. Based on the mechanism, my biggest concern would be a PCL sprain, especially with the knee bent and force driven through the front of the shin. Best-case scenarios would be something more manageable like a knee contusion or posterior capsule irritation/inflammation. And even if this does turn out to be a PCL injury, that does not automatically mean surgery. Many isolated PCL injuries — including some complete tears — can be managed nonoperatively, but they can still cause a multi-week absence depending on the grade, stability, swelling, and how he progresses back into running, cutting, and contact. For now, the MRI is everything. What do you think the diagnosis ends up being? • Knee contusion / posterior capsule irritation • PCL sprain • ACL (unlikely) • Something else? I'm not a doctor.
