Wide receiver Trey Griffey, son of Baseball Hall of Fame outfielder Ken Griffey Jr., is signing with the Miami Dolphins, a source told ESPN’s Adam Schefter on Monday.

Griffey was released by the Indianapolis Colts last week and became a free agent on Monday.

Griffey was an undrafted free agent out of the University of Arizona. He had 79 catches for 1,241 yards and six touchdowns in his college career.
