Washington Redskins quarterback Robert Griffin III's early prognosis is positive, after scans revealed no fracture of his injured ankle.
Griffin III dislocated his left ankle in the Redskins' 41-10 win over the Jacksonville Jaguars on Sunday, and underwent MRI scans on Monday - which cleared him of bone damage.
There is no return date set for the number two draft pick from 2012, with capable back-up Kirk Cousins set to continue to fill the void after impressing when Griffin III departed the field in the first quarter against Jacksonville.
"I think it's too early to tell as far as the timetable is concerned," Washington coach Jay Gruden said.
"All we know is it's not a fracture, we're going put the cast on it for a couple weeks, get more results to Dr. Anderson, see what he says and go from there."
Gruden added DeSean Jackson, who suffered a shoulder injury on Sunday, could face the Philadelphia Eagles in Pennsylvania.
"He's day-to-day," Gruden said of the wide receiver.
"If he can play with the pain, he'll be good to go for Sunday."
