Vikings' head coach Mike Zimmer has yet to commit to a Week 1 starter.
Both Bradford and Shaun Hill are expected to split reps with the first-team offense as practice progresses throughout the week. Week 1's starter will likely depend on how quickly it takes Bradford to become familiar with the offense. The most reasonable expectation in terms of a timetable involves Bradford taking over under center in Week 2, but the Vikings are still hopeful he can figure things out for Week 1.
