This didn't look good.
New York Giants star wide receiver Odell Beckham Jr. left tonight's preseason game against the Cleveland Browns in the second quarter after taking a big shot to his knees.
Beckham pulled in a long reception from Eli Manning and was hit hard by Browns DB Briean Boddy-Calhoun.
Watch his left leg bend a bit.
Beckham was unhappy with the hit from Boddy-Calhoun, and he stared him down as he walked off the field.
Beckham jogged lightly into the tunnel, but then he collapsed to his knees in the tunnel.
A report from ESPN's Lisa Salters indicated Beckham has an ankle injury and was evaluated for a concussion.
Here's hoping he is okay.
