UPDATE (4:27 p.m. PST on Sunday): Grizzlies guard Mike Conley will have surgery Monday to repair multiple fractures of facial bones, according to TNT's Lewis Johnson.
The Grizzlies are one victory versus the Trail Blazers away from setting up a matchup with the Warriors in the Western Conference Semifinals.
But in order to get that win, they'll have to do it without their starting point guard Mike Conley.
The Grizzlies announced that Conley will return to Memphis to be evaluated for a facial injury and has been ruled out for Game 4 on Monday night.
Conley was injured in the third quarter of Game 3 in Portland on Saturday when he collided with Blazers' guard C.J. McCollum and appeared to take an elbow to the face.
His status beyond Monday night is unknown, but The Commercial Appeal is reporting that Conley's injury is "serious" and that there is no timetable for his return.
Conley is averaging 16 points, 3.7 assists and 1.7 rebounds per game during the series against the Blazers.
