UPDATE: The Memphis Grizzlies announced Monday afternoon that starting point guard Mike Conley underwent facial surgery:

The Memphis Grizzlies will be without injured point guard Mike Conley in Game 4 Monday night, as they look to sweep the Portland Trail Blazers.

Conley will reportedly undergo surgery earlier in the day to repair multiple facial fractures.

Conley was hurt with four minutes left in the third quarter of the Grizz’s 115-109 Game 3 win Saturday night.

Per the Commercial Appeal:

But Conley seemed upbeat before returning to Memphis to have the procedure near his left eye. […] “I’ll be good,” Conley wrote in a text message Sunday afternoon before he boarded a plane, while his teammates held a light practice to prepare for an attempt at a sweep.

 

Conley was hurt with four minutes left in the third quarter of Game 3. He was hit by an inadvertent elbow from Blazers guard C.J. McCollum while going after a loose ball. […] Conley fell to his knees and appeared disoriented for several minutes before the team’s athletic trainer helped him to the locker room. Conley was taken to a local medical facility before the game ended in the Moda Center.

 

Griz coach Dave Joerger said Sunday that he didn’t want to speculate on Conley’s possible return until learning the extent of the injury. […] Backup point guard Beno Udrih said he would attempt to play Monday night after sitting out Game 3 with a sprained right ankle. Reserve guard Nick Calathes, who played well in place of Udrih in Game 3, will also play more in Game 4. Calathes scored 13 points to go with four rebounds and three assists in 27 minutes Saturday.
