It’s anybody’s guess when Jerry Remy might resume his duties on NESN. The Red Sox analyst has been on the DL for nearly three weeks, and NESN confirmed Tuesday it will be a while longer before the Remdawg returns to the broadcast booth. Initially, the word was Remy, who has battled a host of health issues in recent years, was suffering from allergies and would miss only a few games. “Have no fear — that’s all it is,’’ tweeted Remy. That was last month. But on June 7, Remy said it was, in fact, more serious than sniffles. “I’ve caught a little pneumonia and it has to run its course,” he tweeted. “It’s not due to anything else, hope to be back soon.” NESN has been mum on the illness, but sent an e-mail Tuesday that said Remy won’t be back until at least next week. Here’s hoping Remdawg returns sooner rather than later because his replacements — a motley crew that includes Jim Rice, Peter Gammons, Dennis Eckersley, Tom Caron, Rob Bradford, and the Globe’s own Nick Cafardo — are not, in the parlance of baseball, everyday players.
