The Angel Reese/Caitlin Clark rivalry's alive and well ... 'cause Angel just committed a hard foul while Clark was going up for a layup -- smacking her in the side of the head.
The foul occurred just moments ago ... with Clark's Indiana Fever up 63-62 over the Chicago Sky in the third quarter, Clark's heading to the hoop when she's taken down by Reese, landing hard on the hardwood.
While at first, it seems like just a tough foul, the referees call for a break in the action to review the blow .
