Saquon Barkley exited with a knee injury from the Week 2 game between the New York Football Giants Chicago Bears. Pending tomorrow's MRI, the news broke out that it is likely an ACL tear.

Many in the Twitterverse are quick to suggest that the lack of the routine preseason activities led to the players not being in optimal condition to play in such demanding conditions. So far, Saquon Barkley and Nick Bosa are the likely-ACL-tears from this year's Week 2, but that live-running injury tracker just keeps on growing...

​I think the NFL's coaches and athletic trainers have a lot of self-reflecting and investigating to do...

Yes, he did. He exited Week 3 in 2019 with a high ankle sprain injury.

Here's the scary part: He's had the same on-and-off ankle sprain injury since his years at Penn State on his right ankle. 

Which knee did he injure today that is suspected with an ACL tear? His right knee.

How did he injure his knee today? Non-contact, with a defensive player applying external force that caused him to push on the right leg with knee valgus forces.

Ankle plantar flexion (to push off the ground).
Right tibia external rotation.
Right femur internal rotation.
