The Memphis Grizzlies are standing under the tough-luck cloud at the moment, having lost three straight games inside the final five seconds. And things got even darker on Tuesday as the team announced that Jaren Jackson Jr. has been diagnosed with a Grade 2 left ankle sprain with no clear timetable for his return.

Jaren Jackson Jr. is that in Memphis. He leads the team in scoring at 22.7 points a game (with 5.8 rebounds) and has become a primary shot creator for the Grizzlies, plus Jackson Jr. will be in the mix (and may be the front runner) for Defensive Player of the Year.

MEMPHIS, Tenn. (AP) — Two-time All-Star Jaren Jackson Jr. is week to week with a sprained left ankle for Memphis after the center-forward was hurt a couple minutes into the Grizzlies’ latest loss.
