Update, 12:35 p.m.:

Washington Redskins quarterback Robert Griffin III said that the MRI exam conducted on his dislocated left ankle showed no fractures on Monday morning.

Griffin still is waiting for orthopedic surgeon Robert Anderson to receive the test results and consult with Washington’s medical staff, but he called outcome, “positive news. … He was watching over me.”

Griffin injured the ankle early in Washington’s 41-10 victory over Jacksonville on Sunday. X-rays showed a dislocation but an MRI exam was needed to determine the full extent of the damage.

Because there is no fracture, which according to orthopedic surgeons is rare, it is believed that Griffin could avoid surgery.

The best-case scenario for the quarterback was a recovery time of six to eight weeks, several surgeons told The Post.

But Griffin said he doesn’t yet know how long he will be sidelined.

It’s the second major injury that Griffin has suffered since the Redskins made him the second overall pick of the 2012 draft, and the third since since 2009 — his sophomore year of college. Griffin tore the anterior cruciate ligament in his right knee both in college and as a rookie.

Dr. Dan Pereles, USA Rugby’s team orthopedic surgeon and medical consultant to the PGA Tour, speculated that Griffin’s recovery time could be shorter because of a dislocation rather than a fracture as well, which would have required surgery.

“If all it is is a pure ankle dislocation, which is really unusual — that’s an incredibly unusual injury for football — you pop it back in, the ligaments scar in place, and you can usually get back to running within six weeks,” Pereles said. “He might be able to get back to play within 12 weeks.”

Redskins coach Jay Gruden will address the media at 3 p.m. and is expected to discuss the timeline for Griffin’s recovery.
