Former Kentucky guard Kellan Grady has signed with the Denver Nuggets as an undrafted free agent. Grady joins Davion Mintz, who signed with the Washington Wizards, in inking an Exhibit 10 deal, which is a 1-year, minimum salary deal that doesn't count against the team's salary cap unless that player makes the regular season roster. Grady will play for the Nuggets in the NBA Summer League and try to earn an invitation to the team's training camp in the fall prior to next season.
