Mike Florio, Pro Football Talk and Bob Kravitz have become cozy. They all agree that Andrew Luck will likely not throw at the Combine although he may do other drills:
Bob Kravitz of the Indianapolis Star told PFT Live on Wednesday that Luck reached out to the Colts for input on whether he should throw, and that the Colts advised him not to. Joe Schad of ESPN.com created the impression, via comments from quarterbacks coach George Whitfield, that Luck had not yet made a final decision. (Schad has since clarified his report to indicate Luck won’t throw.)
Per a source with knowledge of the situation, Luck indeed isn’t planning to throw, but he may do the other Scouting Combine drills.
