Siemian will get the start at quarterback during Saturday's exhibition game against the 49ers, Jeff Legwold of ESPN.com reports.
Siemian is currently listed as a co-starter along with veteran Mark Sanchez on the Broncos' quarterback depth chart, but he's garnered first-team reps throughout this week's practices, along with getting the nod as starter Saturday. The 24-year-old Northwestern product will have to put together a few solid performances throughout the rest of the preseason in order to secure the starting job heading into Week 1, however.
