Memphis Grizzlies point guard Mike Conley underwent successful surgery on Monday to repair a facial fracture near his left eye, according to a published report by The Commercial Appeal.

The dynamic point guard, who has slaughtered the Trail Blazers during the first three games of the teams' best-of-seven Western Conference playoff series, will not play Monday night in Game 4 -- and it's unclear when he will play again in the series.

The team has not released a timeline for Conley's return and, according to the report in The Commercial Appeal, his recovery "could take weeks."

The Grizzlies own a commanding 3-0 lead in the first-round series, but Conley's status moving forward could make things interesting. He's averaging 16.0 points, 3.7 assists and 1.0 steals, but that only begins to reveal his impact in the first three games. His ball-hawking defense has given All-Star Damian Lillard fits and he has steered Memphis' methodical offense with precision.

According to the report, which sites an unnamed source, Conley's surgery went well and he's recovering in Memphis. The team confirmed the surgery late Monday morning in a release, but offered few details, saying only that "additional information will be announced when available." Whenever Conley is cleared to resume basketball-related activities, he likely will have to wear a mask to protect the area under his left eye.

Conley suffered his injury with about four minutes left in the third quarter of Game 3, which the Grizzlies won 115-109, when CJ McCollum inadvertently elbowed him in the face while chasing a loose ball near the sideline.

Conley instantly collapsed to his knees and was tended to by trainers for several minutes, before being helped to the locker room. He was taken to a Portland-area hospital for evaluation that night and, later, on Sunday, he flew to Memphis in preparation for Monday's surgery.

The Grizzlies played 12 games without Conley this season -- including once against the Blazers -- and had success. They went 8-4 in his absence, which featured a 102-98 win over Portland on Jan. 17 in Memphis.

Game 4 is scheduled for 7:30 Monday night at the Moda Center.
