'Entourage' Star Jerry Ferrara -- Face Busted Open During Basketball Game

"Entourage" star Jerry Ferrara is sporting a pretty gnarly gash and bruise under his left eye this morning ... after taking an elbow to the face during a basketball game yesterday.

Ferrara went to Twitter to explain his injuries ... writing, "Caught a elbow playing bball from a very non athletic dude."

Jerry also asked his followers if they think he needs stitches -- though it's unclear if the actor has actually gone to a doctor to get patched up.
