The Colts tweeted the announcement with a picture of a bearded Luck wearing a grey T-shirt.
Luck has been sidelined while recovering from offseason shoulder surgery. He was placed on the physically unable to perform list in July and missed all of training camp.
Although he was removed from the PUP list on Sept. 2, Scott Tolzien started in Sunday's 46-9 loss to the Los Angeles Rams. Tolzien completed 9 of 18 passes for 128 yards and two interceptions before being benched in favor of Jacoby Brissett.
Pagano said Monday that the team is still evaluating its immediate options at the quarterback position moving forward.
The first overall pick in the 2012 draft, Luck threw for 4,240 yards and 31 touchdowns last season.
