The timetable for Andrew Luck was always tight.

Now he will need some good fortune to play in the Colts’ season opener.

While Luck is undoubtedly doing everything he can to play Sept. 10 against the Rams, time is simply running out.

Colts owner Jim Irsay acknowledged Sunday that it is not certain Luck will be ready for the season opener.


Luck has been throwing, but not in practice. That is a vast difference.

Throwing in a rehab setting is controlled. Throwing in team drills is mimicking game conditions (stresses on the arm). Think of the difference between warming up in basketball by taking free throws versus taking a jump shot coming off a screen with a defender coming at you.

Given that all along it has been known recovery from his surgery usually involves six weeks of throwing before being ready to actually play in a game, the fact Luck has not thrown in practice to this point makes it more likely Scott Tolzien is starting for the Colts in Week 1.
