The 82-year-old Hall of Famer arrived in the desert Sunday to call his first game of the spring.
"I'm supposed to cut back on dangling participles, and I'm not allowed to split any infinitives for at least another week," Scully told reporters inside the Dodgers' spring training complex.
Scully said he was never in a life-threatening situation. Feeling the effects of a cold, he was walking across a marble floor to his bathroom when he blacked out.
When he regained consciousness, he said his wife was calling 911 and there was blood on the floor. At the hospital, Scully received five staples in the back of his head. He also had a large bruise on the back of his right arm and has some soreness in his back.
"I was embarrassed, and I am embarrassed because it was such a dumb thing to have happen," Scully said. "I am embarrassed over all the fuss and feathers. But somehow, I did it to myself, and I hope not to do it again."
Sunday's Dodgers game against the Cleveland Indians was the first of two Scully will broadcast this spring as he enters his 61st season with the club.
