As the Celtics head to Atlanta for Games 3 and 4 of their Eastern Conference first-round playoff series, NBC Sports Boston is scrambling to find a fill-in announcer. Legendary play-by-play voice Mike Gorman, who recently had surgery for a detached retina, hasn't been cleared to fly. Meanwhile, Sean Grande, the team's current radio play-by-play voice, has committed to another event and isn't available for those games. NBC Sports Boston has confirmed that rather than bringing in an unfamiliar play-by-play voice, analysts Brian Scalabrine and Eddie House will call both games. "We're reaching out to a bunch of people to have some fun with it," said Scalabrine on his SiriusXM NBA Radio show. Brian Scalabrine is the lead analyst for NBC Sports Boston's game coverage of the Celtics and would have been the perfect option to call the games, but Scalabrine's partner, Mike Gorman, is currently not available for the playoff games. Jon Wallach will handle the radio call in Grande's absence, while ESPN and TNT will cover Game 3 and 4, respectively. If the series lasts long, Grande is expected to call Game 6 in Atlanta for NBC Sports Boston.
