INDIANAPOLIS (AP) Andrew Luck was listed as a limited participant in practice Thursday for the second straight day with a sore right shoulder.
He's still expected to start Sunday against Jacksonville (1-2).
Luck and coach Chuck Pagano do not usually speak to reporters after Thursday practices, and offensive coordinator Pep Hamilton deferred all comments about injuries to Pagano.
Backup quarterback Matt Hasselbeck said his workload was about the same as Wednesday, when Luck took a rare day off. Hasselbeck said he was certain Luck would play.
Luck was injured in last weekend's 35-33 at Tennessee.
The fourth-year quarterback has never missed a start since Indy (1-2) took him with the first pick of the 2012 draft.
