The San Francisco 49ers have been practicing at The Greenbrier in White Sulphur Springs this week. San Francisco plays for a second straight week at Met Life Stadium in New York this weekend against the Giants. Last Sunday, the 49ers beat the Jets there, and decided to stay on the east coast rather than take the long flight back to California. The Greenbrier has been host to NFL training camps for both the New Orleans Saints and Houston Texans in the past.
