Devin Booker will miss at least four weeks of action after suffering a groin strain.
The Phoenix Suns star pulled up just four minutes into the 128-125 overtime defeat to the Denver Nuggets on Christmas Day.
Booker had missed the previous three games with groin soreness, and he appeared to suffer a recurrence early on at Ball Arena before leaving the court.
The Suns confirmed on Wednesday that Booker will miss at least four weeks, at which time he will undergo further evaluation.
The 26-year-old has been in fine form this season, averaging a career-high 27.1 points per game, and he scored 58 points against the New Orleans Pelicans in his previous appearance prior to the brief cameo against the Nuggets.
Booker will have to wait to surpass Steve Nash to claim top spot for franchise three-pointers, needing to add just seven more to his current total of 1,045.
