Shanahan says Griffin III is 'feeling good' after concussion

Washington Redskins coach Mike Shanahan said on Monday that quarterback Robert Griffin III is "feeling good" after suffering a concussion during Sunday's game against the Atlanta Falcons.

Griffin left the contest after taking a hit to the head by Falcons linebacker Sean Weatherspoon.

Shanahan said Griffin has "no dizziness, no headaches, and no vomiting."

Griffin was exhibiting no post-concussion symptoms on Monday, a day of rest and testing for the rookie quarterback.

"We're going to go through the process with Robert, hopefully there is no setback and he's ready to go," Shanahan said about Griffin's status for this week's game against Minnesota.

Shanahan also announced that safety Brandon Meriweather has been diagnosed with MCL (2nd degree) and PCL (3rd degree) injuries. He will not be eligible to return for another four weeks.
