Boston Celtics guard Jaylen Brown has been in and out of the rotation as of late, but he might be down for the count after injuring both his ankles on Sunday.

Brown returned to the lineup against the Oklahoma City Thunder after missing Friday's game against the Atlanta Hawks. However, he revealed he rolled his left ankle “trying to compensate” for a previously injured right ankle.

Head coach Brad Stevens said the severity is unknown, though Brown was able to finish the game.

Brown finished the game with 17 points, three rebounds and two assists in 34 minutes of action.

The Celtics have been unable to avoid a slew of injuries. Sunday marked the first time in weeks that essentially all of the mainstays in the rotation were healthy. However, that is subject to change once again with Brown's status in question.

In fact, it is entirely possible the Celtics elect to hold Brown out of their final two games before the All-Star break next weekend.

These past few weeks have been frustrating for Brown. He was mostly healthy through the first few months of the season, but he had missed five of Boston's last 12 games prior to Sunday due to the ankle as well as a thumb injury.

Brown's progression has been a major factor in the Celtics' success this season. The 23-year-old entered Sunday's contest averaging 20.3 points, 6.5 rebounds and 2.2 assists while shooting nearly 50 percent from the field, including 37.5 percent from beyond the arc.

Jaylen Brown had been one of the names under consideration for an All-Star reserve spot, ultimately falling just short of being selected.
