Robert Griffin III signs with Redskins

ASHBURN, Va., July 18 (UPI) -- Quarterback Robert Griffin III, the No. 2 overall pick in the 2012 NFL draft, has agreed to terms with the Washington Redskins.

The agreement, signed by Griffin Wednesday, is reportedly a four-year deal worth about $21 million. He was expected to join the team's rookie camp, which began Monday.

"Well people ... It's Time to go to Work!!!" Griffin posted Wednesday on his Twitter account. "Off the unemployment line and oh yea #HTTR!!!!"

"HTTR" refers to "Hail to the Redskins," the team's fight song.

He started 11 of 12 games in 2008, his freshman year at Baylor, but injured his knee and missed almost all of the 2009 season. He was the Bears' starting quarterback in 2010 and '11.

For his career, Griffin completed 776-of-1,159 passes for 10,071 yards and 78 touchdowns. He rushed 510 times for a total of 2,199 yards and 32 touchdowns.
