Minnesota Vikings quarterback Tommy Kramer has been arrested by Bloomington, Minn., police for alleged drunk driving.

Kramer, 32, who was treated at a California hospital for alcohol problems after the 1981 NFL season, was pulled over late Friday night and taken to a detoxification and evaluation center, police said. He left the hospital yesterday morning and retrieved his car from the Bloomington Police Department parking lot. He is scheduled to appear in court Aug. 6.

The team's training camp begins next week, and one teammate, punter Greg Coleman, said, Kramer's arrest "catches me by surprise because Tommy's been working very hard. He's in the best shape of his career. He's been running, lifting, throwing . . . Who's to say? It may have just been one of those nights."

Rickey Young, a close friend and former teammate, said Kramer "has changed quite a bit and he's not the same partier" he had been. "I'm sure he just left a golf tournament and just had a couple of beers. I don't think he has, per se, a problem." . . .

The City of St. Louis has filed suit against the football Cardinals to keep the team at Busch Stadium. The suit seeks to enforce the team's stadium lease, which is in effect until 1996. Club owner William V. Bidwill has signed an agreement in principle to move it to a proposed domed facility in the suburbs . . .

Free-agent quarterback Ron Jaworski says his agent and the Green Bay Packers could agree on a contract as early as next week.
