Heinicke (ankle) returned to practice Wednesday after a lengthy recovery stemming from July foot surgery, Matt Vensel of the Star Tribune reports.

Heinicke has a three-week window for the Vikings to either activate him from the reserve/NFI list, waive him, or send him to IR. If he's activated he'll likely serve as the No. 3 option at quarterback behind starter Sam Bradford and veteran backup Shaun Hill.
