In a long-expected move, the Minnesota Vikings released quarterback Brad Johnson and made the 15-year veteran an unrestricted free agent.

The 49ers promoted quarterbacks coach Jim Hostler to offensive coordinator Tuesday, the fifth coach to hold that job in five seasons in San Francisco. Coach Mike Nolan chose Hostler to replace Norv Turner, who became the San Diego Chargers’ head coach nearly two weeks ago, after interviewing each of the five offensive assistants Turner left behind.
