Steve Rosenbloom, former general manager of the New Orleans Saints and the Los Angeles Rams, is in a New Orleans hospital recovering from what he has described as a freakish automobile accident last Sunday in which he suffered a fractured skull. His former wife, Renee Rosenbloom, who has been with him since the accident, said last night that Rosenbloom was driving a 1967 Glassic roadster, a fiberglass-bodied replica of a 1931 Ford. Mrs. Rosenbloom said her husband told her he fell out of the car, which had no locks, and curtains instead of windows, when it ran off a curve on a cobble-stoned street and hit a loading dock.

She said he did not suspect foul play. The incident occurred a day before the telecast of a documentary suggesting that Rosenbloom's father, Carroll Rosenbloom, the Rams' owner who drowned in 1979, might have been murdered as a result of his gambling activities. Steve Rosenbloom said in that telecast that he believed his father had been slain.
