Robert Griffin III will not be placed on season-ending IR

Redskins quarterback Robert Griffin III says an MRI on his injured ankle did not reveal a fracture. Griffin dislocated his ankle in Sunday's win over the Jaguars and was carted off the field.

Redskins quarterback Robert Griffin III will not be placed on season-ending injured reserve after dislocating his ankle in Sunday's win over the Jaguars, coach Jay Gruden said on Monday.

Gruden said he does not have a timeline for Griffin's possible return this season and that the Redskins may bring in another quarterback while Griffin rehabs the ankle.

Earlier, Griffin said that an MRI on the ankle did not reveal a fracture, according to Mike Jones of The Washington Post. 

"[I]t is believed that Griffin could avoid surgery," Jones wrote.

Griffin was carted off the field and replaced by Kirk Cousins, who completed 22 of 33 passes for 250 yards and two touchdowns. 

Washington also lost receiver DeSean Jackson to a shoulder injury Sunday, but Jackson reportedly has "no serious structural damage."

Griffin was on crutches and wearing a cast on his foot in the Washington facility Monday. 

The best case scenario for Griffin's recovery would put him out for six to eight weeks, several surgeons told the Post.

Gruden: QB @RGIII has a dislocated, and not broken, left ankle. Does not have a timeline for his return; could be this season.
