ESPN's Adam Schefter reports Andrew Luck (shoulder) is "legitimately questionable" for Week 4.
It had been assumed the Colts were just exercising caution with their franchise quarterback, but it appears he's actually having difficulty throwing.
Per Schefter, Luck was "shut down" midway through Thursday's practice, and will throw little, "if at all," before Sunday's game against the Jaguars. Schefter reports the fact that the Colts have the Thursday night game in Week 5 will be part of their decision-making process.
