The “lower leg” injury for Colts quarterback Andrew Luck continues to get more mysterious as the club remains vague about the nature of the issue and the long-term prognosis.

Luck appears doubtful to play in the preseason, and that's worth keeping an eye on for Chiefs fans. The Colts are due to visit Kansas City in Week 5 for a rematch of last year's Divisional Playoff game, and the game looms as a likely playoff bellwether for both teams, assuming Luck is healthy. https://www.usatoday.com/story/sports/nfl/colts/2019/08/13/andrew-luck-injury-2019-chris-ballard-colts-update/2004730001/
