Brent Grimes didn't suffer any structural damage to the right knee injury he suffered in last Sunday's 27-14 loss to the New York Jets.
According to a source, an MRI taken earlier this week revealed that Grimes simply sprained his right knee. Grimes, 32, is supposedly experiencing some discomfort in the knee, but that might subside by the time the Dolphins conclude the bye week and play the Tennessee Titans on Oct. 18.
Grimes, who has contributed 12 tackles and one interception in the four games he's played this season, has started every game he's played for the Dolphins the past three seasons. So he'll likely try to play through the injury, but his playing and practicing status will likely be determined by Miami's medical staff.
