The 49ers elevated Carlson from the practice squad to the active roster Saturday, in preparation for him to start Sunday's game against the Cowboys, Matt Barrows of The Athletic reports.
Carlson will get another chance to start for San Francisco due to Jake Moody (ankle) being ruled out for Week 8 and Matthew Wright (shoulder) on injured reserve. Carlson, a second-year pro, converted both of his field-goal tries Week 7 against the Chiefs, but he missed his lone extra-point attempt.
