Washington Redskins quarterback Robert Griffin III was cleared to play by team doctors on Thursday evening, according to Redskins reporter George Wallace.

Redskin's team president Bruce Allen made the announcement. Griffin suffered a concussion during the second preseason game against the Detroit Lions. He took some bad hits throughout that game, and he has taken many bad hits throughout his career, and has had injury problems since entering the league.

After winning the Heisman at Baylor and being drafted in the first round by the Redskins, Griffin exploded onto the NFL scene in 2012. In his first season as starting quarterback he posted a 9-6 record that got the Redskins to the playoffs. Since then, as a starter, he's has gone 5-15, and has seemed to get worse with time.

Kirk Cousins will be the starting quarterback for the Redskins against the Miami Dolphins on Sunday.

"Robert has done some great things no question, we have total faith in all three of them.  But moving forward with all the things we've studied over the course of training camp and OTA's, we just feel like Kirk has earned the right to be the starting quarterback for 2015," said head coach Jay Gruden, via NFL.com.

The Redskins have Griffin listed third on their depth chart as of right now, and that is not surprising, with him coming back from a head injury. Colt McCoy is second on the depth chart, and showed last season that he can play in the league. All three quarterbacks have losing records in the NFL, and Gruden will likely have to work some magic to turn this team into a winning one.

Griffin is set to make $16 million next season, a high priced for a backup quarterback. Griffin has been cleared to play, but it is unknown when he'll be on the field next. The best chance Griffin has to play is if the Redskins are losing, which could entail Kirk Cousins under-performing.
