New Jersey Nets center Brook Lopez is expected to miss three weeks with a sprained right ankle, the team announced on Monday.

Lopez will be in a walking boot, and the Nets will update his status on March 23.

The 23-year-old suffered the injury in the third quarter of Sunday night’s game in Charlotte and did not return. He underwent X-rays later that night, but the team did not reveal the news until Monday.
