Hampered by knee and leg injuries earlier in his NBA career, Lakers center Brook Lopez has been relatively healthy in recent years, having not missed more than 10 games in a season since 2013/14. However, that streak appears to be in jeopardy.

Lopez left Monday’s game with an ankle injury, and has been diagnosed with a moderate ankle sprain, the team announced today in a press release. According to the Lakers, Lopez will be reevaluated in three weeks, so he’ll be sidelined until sometime in the new year.
