INDIANAPOLIS — The Indianapolis Colts have signed 18 undrafted rookies, including receivers Trey Griffey and Jerome Lane, whose fathers were pro athletes.

Griffey, the son of baseball Hall of Famer Ken Griffey Jr., finished his career at Arizona with 79 catches, 1,241 yards and six TD catches. He was selected by the Seattle Mariners in the 2016 baseball draft.

If you question whether he make it in the NFL as an undrafted rookie, just remember this. Seattle Seahawks No. 1 receiver Doug Baldwin was also undrafted out of Stanford.

The Seahawks host the Colts on Oct. 1. That means there's a chance dad, who is also an avid photographer and has shot many of Griffey's games, could be on the sidelines at CenturyLink Field if 

Lane's father played in the NBA and broke a backboard in college at Pitt.

Indy also signed offensive linemen Deyshawn Bond, Christopher Muller and Jerry Ugokwe; tight ends Darrell Daniels and Colin Jeter; receivers Johnathan "Bug" Howard and Bruce "JoJo" Natson; running backs Dalton Crossan and Brandon Radcliff; long snapper Thomas Hennessy; cornerback Reginald Porter; punter Rigoberto Sanchez; linebacker Garrett Sickels; defensive end Jhaustin Thomas and quarterback Phillip Walker.
