Langford is questionable for Saturday's game against the Bucks due to left Achilles tendinopathy.
Langford is one of six Celtics listed as questionable for Saturday, in addition to eight players already ruled out. The 22-year-old started last time out and had 11 points (5-8 FG, 1-3 3Pt, 1-1 FT), two assists and one block in 31 minutes, and he could be similarly involved Saturday if cleared to play.
