Ricky Rubio

Minnesota Timberwolves rookie point guard Ricky Rubio will have an MRI on his left knee Saturday morning amid fears he tore his anterior cruciate ligament, a league source told Yahoo! Sports.

“Possible ACL,” the source briefed on Rubio’s condition said. “We’ll know more after the MRI. … There’s a lot of worry right now.”

Rubio’s knee buckled with 16.4 seconds left in the Timberwolves’ loss to the Los Angeles Lakers Friday night in Minneapolis.
