Celtics legend Tommy Heinsohn said he will undergo further testing Tuesday related to what appears to be a mild case of sleep apnea, and he is hopeful that he will be able to return to the broadcast booth soon. Heinsohn said he will be fitted with a new oxygen mask that will be adjusted to the appropriate pressure to help treat his condition. The belief is that better nights of sleep with the mask will reduce the fatigue he has been experiencing.
“Hopefully, that will allow me to feel refreshed in the morning and not feel my 84 years,’’ Heinsohn said by phone this weekend.
