Andrew Luck Watch 2018 is truly underway.
The Indianapolis Colts star quarterback's rehab from a shoulder injury that robbed him of the entire 2017 campaign will be one of the defining stories of the offseason.
While Luck didn't go into specifics, NFL Network's Ian Rapoport reports the star signal-caller is throwing weighted balls heavier than footballs rather than tossing around a normal football.
It's a significant step for the 2012 No. 1 pick, who briefly returned to practice in November and was seen throwing before again experiencing pain in his shoulder, forcing Indy to place him on injured reserve.
