As the blogosphere buzzes with unconfirmed rumors that Boston Red Sox general manager Theo Epstein was seen in Chicago while nobody will even say if he has permission to talk to the Chicago Cubs, one more solid tidbit came out on Tuesday.

WEEI sports radio in Boston cites a major league source as saying the Red Sox will not bring in candidates to interview for their vacant managerial job until they know what Epstein is doing. The source told the radio station that the Red Sox continue to perform due diligence on potential managerial candidates.

The news at least indicates that something is going on with Epstein and the Red Sox -- whether that means that he is indeed speaking to the Cubs, or that the GM and Red Sox are haggling over a contract extension.

Red Sox owner John Henry said last week that Epstein will not be the team's GM forever, just as manager Terry Francona had reached his shelf life in Boston.

Cubs chairman Tom Ricketts has been mum on a possible Epstein pursuit, saying a while back that he would speak to a "handful" of candidates.

As for the guy who claims he saw Epstein in Chicago, it's interesting that in the age of smartphones he didn't think to take his picture. He said Monday on "The Waddle & Silvy Show" on ESPN 1000 that he didn't want to be "that guy" to stick a phone in Epstein's face. But he didn't mind being the guy to go up and ask if the person in question was Theo Epstein. The person said he wasn't but that he gets the question a lot.

It's hard to know what to believe, considering someone claimed to have seen then-free agent LeBron James house-hunting in the Chicago area last year before he announced he was going to Miami.
