The 32-year-old actor severely cut himself on the set of his new film, in which he plays a struggling crime reporter in Los Angeles, reported Us magazine.
"Jake was indeed filming 'Nightcrawler' when during the shooting of an intense scene his character purposefully banged his hand into the mirror," his representative said.
"Unfortunately the mirror broke and Jake's hand was badly cut up. He got numerous stitches at the ER and was released. He already returned to set for work."
