The odds of Andrew Luck being ready for Week 1 of the regular season are appearing less likely.

"Really no further updates. All we have right now is a combination of full-speed movement and pain threshold," Frank Reich said.

Luck has practiced only three times -- none of them as a full participant -- since April due to what was originally diagnosed as a calf injury. 

Jacoby Brissett will continue to be the Colts' starting quarterback if Luck, who has missed 26 games since 2015, remains out.
