The Boston Celtics got key contributions from the bench guys as they narrowly best the Los Angeles Clippers 117-113 in overtime.

The defending champions start up a back-to-back in Los Angeles on Wednesday, Jan. 22 when the Boston Celtics visit the LA Clippers at the Intuit Dome in Inglewood, Calif.

Boston will need to be vigilant that old habits vs. banged-up and lesser ball clubs don't make a winnable game into a struggle -- or worse, a loss.
