INDIANAPOLIS – For a second straight day, Andrew Luck was not present during the open media portion of practice.
With Luck not at Tuesday's open portion of practice, Scott Tolzien and Stephen Morris (practice squad) were the quarterbacks working.
Chuck Pagano's next update on Luck will come later Tuesday afternoon.
Luck missed Monday's practice after he entered the concussion protocol following Sunday's win over the Titans.
If Luck is not cleared by Thursday, expect Tolzien to be the starting quarterback when the Colts (5-5) take on the Steelers (5-5).
