"This trade gives us a chance to improve in key areas moving forward," Indianapolis general manager Ryan Grigson said in a team release. "David is a very competitive football player, and we welcome his style of play and energy. At the same time, we wish Delone well with his opportunity to play for another first-class organization, and we thank him for his efforts."
This is the second trade between the Colts and Ravens this offseason. Indianapolis previously sent backup center A.Q. Shipley to Baltimore for a conditional 2014 seventh-round draft pick.
