FILE - In this Sept. 18, 2016, file photo, Cleveland Browns quarterback Robert Griffin III walks the field with his arm in a sling during practice before an NFL football game against the Baltimore Ravens, in Cleveland. A person familiar with the decision says the Cleveland Browns are releasing quarterback Robert Griffin III after one injury-marred season. Griffin is being let go one day before he would have been due a $750,000 roster bonus, said the person who spoke Friday, March 10, 2017, to the Associated Press on condition of anonymity because the team has not announced the move.
