Manny Machado’s Knee Injury is Not for the Faint of Heart

As he approached first base, Machado looked up, causing him to awkwardly clip the edge of the bag. His knee buckled severely and he collapsed to the ground in great pain. 

Yeah, doesn't look good. The full extent of the injury won't be known for some time, but here's hoping it just looked bad.
