Warning: This rumor was originally reported on the shameless scandalmonger site Boston Dirt Dogs. Therefore it's false. Here's an update from that same site later.
Breaking News Report:
Foulke Says He Didn't Fly to Alabama to Have His Arm Examined on Monday.
Cooperstown Store Owner Stands By Comments from Foulke Agent
Update: Keith Foulke told WEEI's Dale and Holley today that he did not go to Alabama on Monday. Boston Dirt Dogs spoke again to Ron Brown, owner of The Factory Store in Cooperstown where Foulke was contracted to appear on Monday, who said "I've known Jack (Jack Berke, Foulke's representative) a long time and I don't think he would make that up. Somebody's pulling a fib here but I have no reason to be pulling a fib. Maybe he didn't go (to Alabama), but the agent miscommunicated. Maybe he didn't want to show, or come to Cooperstown, but the event is over and done but that's what I heard and that's what I told people."
Their sources of friends of relatives who might know something, but actually don't 99% of the time.
Jack Berke? Is not a baseball agent. He's runs autograph shows, one of which Foulke bailed on. Dirt Dogs misleadingly refers to him as "Foulke's representative", and Rotoworld morphs that understandably into "Foulke's agent".
In conclusion, I would not believe Boston Dirt Dogs if they reported that the Red Sox won the World Series last year.
