A Baltimore TV station reported yesterday that the Atlanta Falcons and St. Louis Cardinals football teams have approached Maryland authorities about the possibility of moving their teams to Baltimore, where a new football stadium is in the works.

Both NFL teams want new, larger stadiums. Both have made inquiries about the "ground rules" for negotiating contracts for moving to Baltimore, but no formal talks have taken place, WBAL-TV reported.

"I was told that {the Cardinals' inquiry} was a secret and nobody knew about it except the couple people that told me," Maryland Gov. William Donald Schaefer told the station . . .

The St. Louis Post-Dispatch reported that the Cardinals can get a long-term lease by moving to Tempe, Ariz. University officials denied the story . . .

The NFL caught Coach John Robinson of the Rams trying to slip 13 veterans in this weekend's game. He put their names on the list of players who beat Wednesday's deadline to return to work, rationalizing that someone had told him the 13 "had expressed an interest" in going back to work. But according to the NFL, only quarterback Jim Everett will be eligible, because he had met with Robinson before the deadline . . .

Bo Jackson, most recently of baseball's Kansas City Royals, still hasn't reported to the Los Angeles Raiders. It's believed he'll report once technicalities of his eligibility are worked out.
