INDIANAPOLIS – The roster turnover continues for the Indianapolis Colts, and the latest change has brought them an interesting prospect at a key position.

The Colts signed rookie quarterback Brad Kaaya off the Detroit Lions’ practice squad on Wednesday, giving him the spot once occupied by cornerback Rashaan Melvin, who was moved to injured reserve (hand).

Kaaya, the Lions' sixth-round pick this year from Miami (Fla.), gives the Colts a quarterback they can continue to evaluate and develop through the offseason, potentially putting him in contention to be on the roster with Andrew Luck and Jacoby Brissett next year. The Colts kept a third quarterback, Phillip Walker, on their practice squad throughout the 2017 season.

Kaaya could have elected to stay in Detroit, which likely would have kept him on through the offseason heading into training camp 2018. But Kaaya is taking a chance on the Colts based on the feedback he got from General Manager Chris Ballard and Vice President of Player Personnel Rex Hogan.

“From what my agent told me from (his conversations) with Chris Ballard and Rex, they were saying some pretty good things and it was an opportunity for me to continue my development,” Kaaya said, “and, if I hold up my end of the bargain, do my best to make the team.”

That’s a clear reference to 2018, meaning this isn’t some one-week tryout for Kaaya. The Colts had an eye on him prior to the draft -- Kaaya said he was in regular contact with quarterbacks coach Brian Schottenheimer back in the spring -- and Ballard has shown he will make an effort to acquire players he once had an affinity for.

Kaaya, who spent six weeks on active rosters this season in Carolina and Detroit, said he’s learned quite a bit from bouncing between cities in 2017. The Colts will be his third team this year.

“It’s been a true taste of the NFL,” Kaaya said. “I think it’s prepared me and I think helped me mature real fast.”
