Washington Redskins' quarterback Robert Griffin III followed Wednesday's practice with another on Thursday, according to several sources.
Griffin's status for Sunday's game against the Minnesota Vikings remains uncertain after he was knocked out and suffered a concussion last Sunday against the Atlanta Falcons. Griffin will undergo more medical tests to gauge his ability to return following his second concussion in less than a year.
If Griffin is not cleared to play, Redskins fans are already debating who should play quarterback against the Vikings: rookie Kirk Cousins or veteran Rex Grossman. Cousins completed five of nine passes with a touchdown and two interceptions against the Falcons.
Head coach Mike Shanahan isn't tipping his hand on the team's backup plans.
From NBC Washington:
"You have to look at both ends of it," Shanahan said regarding preparations at the quarterback situation.
Shanahan didn't indicate how the remaining reps were split between Cousins and Grossman. And while most of us are familiar with Grossman's game -- rare moments of brilliance sandwiched around long stretches of mediocrity -- all we've seen from Cousins came in the quarter-and-a-half of work he got in Griffin's absence last Sunday.
