Jared Leto in Chapter 2705 Mar. 2007 (Bang) - The Fight Club star was performing with his band 30 Seconds to Mars when he ran into the Texan crowd and was "rushed by fans". He suffered a broken nose and minor injuries to his foot, face and body.
Tour manager Kevin Lyman said: "In all my 25 years of producing shows this as one of the scariest moments I have seen. We all hope Jared has a speedy recovery."
Despite his injuries, Leto, 35, finished the show, even declaring it one of his best ever.
He later checked into hospital to discover if his injuries required surgery.
The Chapter 27 star and his band were performing in the Taste of Chaos tour, with other band including The Used and Senses Fail.
Last October, Leto had an altercation with Elijah Wood at an MTV awards ceremony after Elijah told him he wasn't impressed with his band.
Wood said: "He was basically upset at the fact that I said I didn't like his band.
"He said that initially and then walked away. I guess he thought I was laughing at him, but I was more shell-shocked and telling people around me, 'Whoa, I just got told off by Jared Leto for not liking his band.' And that's when he came back and grabbed me."
