The Indianapolis Colts are adding the son of an MLB legend to the mix at wide receiver.

Among the many undrafted players joining the Colts during the priority free-agent period is Trey Griffey, son of baseball Hall of Famer Ken Griffey Jr., according to Mike Wells of ESPN.

Griffey makes the jump to the NFL after four seasons at Arizona, where he racked up a total of 79 receptions for 1,241 yards and six touchdowns.

The production wasn't enough to have his name called during the draft this weekend, but he proved at his March pro day that he has more than enough athleticism to contribute at the professional level.

Griffey will have a chance to make his case for a roster spot in offseason workouts and training camp.

Griffey Jr., whose 630 career home runs puts him sixth among MLB's all-time leaders, was inducted into the National Baseball Hall of Fame last July after a record 99.3 percent share of the vote.

In a move to honor their longtime superstar, the Seattle Mariners drafted Trey in the 24th round of the 2016 MLB Draft.
