SACRAMENTO — Celtics shooting guard Avery Bradley remained in Boston on Tuesday, still bothered by lingering soreness from his Achilles’ strain, as the Celtics departed for this four-game road trip.

“He’s had a couple of moments where it’s been two steps forward and a step back,” Celtics coach Brad Stevens said. “Still structurally all good. The MRIs and scans and everything have looked good all along. Just obviously a strain and something that like we said earlier, it’s gonna be a progression to get back.

“And our doctor met with him last night along with our training staff, and everybody else and made the call to keep him back. I originally thought he was coming on the trip yesterday afternoon. So that was a last, last-minute call.”

Bradley has missed 13 of the Celtics’ last 14 games. Boston has found a rhythm recently, however, as it enters Wednesday night’s game against the Kings riding a seven-game winning streak.

Stevens said it appears likely Bradley will be sidelined until after the All-Star break.

“If he comes back before that, it might be a surprise now, just because of the fact that by the time we get back in Boston we don’t have a practice,” Stevens said. “And I’m guessing that would be part of the progression.

“But don’t hold me to that because I’m not on the medical staff, and if they feel like he’s progressing at the right rate and want to fly him to Dallas for practice [on Sunday] and then get a warm-up in the day before the game, and maybe he does play next week. I would think that it’s unlikely.”
