Beverley, who started the game, left with 3 minutes, 54 seconds remaining in the first quarter with what the team called soreness in the calf. He was listed as questionable to return before being ruled out in the third quarter.
"I don't think it's bad," Clippers coach Doc Rivers said after the Suns stunned the Clippers 117-115 on Devin Booker's buzzer-beater. "We're going to be very cautious, I can tell you that."
Beverley had four points and two rebounds in his third game back since leaving the team briefly to tend to an excused family emergency. His injury comes as the Clippers were getting closer to being whole. Lou Williams rejoined the team for his NBA restart debut against the Suns after spending 10 days in quarantine following his departure from the bubble to tend to a family emergency.
Forward Montrezl Harrell is still not with the team, and Rivers said there is no update on a timetable for his return yet. Harrell left the team on July 17 to tend to a family emergency. The forward recently posted on social media that his grandmother passed away.
