Joe Mazzulla returns to coach ...

Interim head coach Joe Mazzulla returned for the Boston Celtics on Sunday night after missing a pair of games due to an eye injury. Mazzulla revealed Sunday, before Boston took on the Denver Nuggets at Ball Arena, that he was hit in the face while playing in a pickup game last week at TD Garden. Mazzulla was hit in the eye Tuesday afternoon, just hours before the Celtics were due to host the Houston Rockets. He met with reporters normally before that game, but ended up not coaching. Mazzulla was diagnosed with a corneal abrasion in both of his eyes. Assistant Damon Stoudamire took his place and led the Celtics to a pair of wins in his absence, first against the Rockets and then against the Los Angeles Clippers. Mazzulla said he couldn’t really see much of anything on Tuesday night, so he wasn’t able to watch film from the Houston game. Even opening his eyes was tough. Mazzulla replaced Ime Udoka, who was suspended by the franchise before the season started. Boston entered Sunday’s game against the Nuggets, which is the first of a four-game trip, on a four-game win streak and a league-best 26-10 record.
