News come via Boston.com (BTW: We think they mean Lawrence and not Tim Frank.): “Celtics’ coach Doc Rivers underwent minor throat surgery Sunday morning at Massachusetts General Hospital and missed practice Monday. Rivers could return for the Celtics’ game against New York Wednesday. Assistant coach Tim Frank said the operation was planned and Rivers could be back as soon as Tuesday’s practice session. ‘Right now the doctor doesn’t want him using his voice,’ Frank said of Rivers. ‘Everything looks good and he’s looking forward to getting back. They just want him to rest his voice box. Obviously, he’ll be using it quite a bunch, so he’ll have plenty of time.’”
