Washington Redskins quarterback Robert Griffin III has offered to race Pierre Garcon to prove his knee injury hasn't affected his speed.
Griffin is currently confined to a knee brace following off-season surgery on a reoccurring knee problem.
A number of people, including Pierre Garcon, have claimed that Griffin is unlikely to rekindle the same speed following the surgery.
"Robert obviously can't run as fast as he did last year because of his knee brace and his knee," Garcon told ESPN980 Radio on Tuesday.
However, the 23-year-old has rejected the claims and has offered to race the Redskins wide receiver to to prove his fitness.
Griffin said to reporters: "There's no knee issue. I love my receiver. If he wants to race, then we can race."
It remains though, a fact that Griffin hasn't been running as much so far this season and many are speculating that he doesn't have the confidence in his knee to go all out.
But Griffin has again rejected claims and said that he will go all-out when the opportunity comes.
"It just hasn't presented itself," Griffin said. "We've hurt ourselves by getting behind so early."
