The embattled actor, who stars in British director Andrea Arnold's indie, "sustained minimal injuries" while filming, his rep said in a statement to The Times on Wednesday.
"As protocol, production sought out medical attention, and Shia received stitches on his hand and for a laceration on his head," his publicist, Melissa Kates, said.
The 29-year-old is due back on the set Thursday.
Variety reported that the injury occurred in North Dakota while LaBeouf was shooting a scene that called for him to put his head through a glass window — and that's how he cut his head and index finger.
The actor reportedly was treated at a hospital and received 20 stitches and 13 staples, according to TMZ, which first reported the mishap.
