The Portland Trail Blazers say an MRI on star guard Damian Lillard confirmed a right groin strain, and he will be re-evaluated in one week.

Lillard suffered the injury on a drive to the basket in Thursday night's loss to the Memphis Grizzlies. He attempted a tough shot around Memphis big man Jonas Valanciunas, then landed awkwardly with about 3:22 left and didn't return.

After the game, Lillard said the injury would keep him out of this weekend's All-Star Game and 3-point contest. The NBA on Thursday named the Phoenix Suns' Devin Booker his replacement for both.

Due to the All-Star break, the Trail Blazers aren't back in action until Feb. 21, against the New Orleans Pelicans (10:30 p.m. ET, ESPN).
