Clark will fill in as the starting safety in Week 13 against the Falcons, Jamison Hensley of ESPN.com reports.
Tony Jefferson (ankle) would have been the starter Sunday, but he was unable to log a practice all week and has been ruled out. Clark logged four tackles (three solo) over a season-high 27 defensive snaps against the Raiders in Week 12.
Clark will start against the Falcons on Sunday if Tony Jefferson (ankle) is unable to suit up, Jeff Zrebiec of The Athletic reports.
Clark's opportunity comes with starter Tony Jefferson nursing an ankle injury of undisclosed severity. The 23-year-old played 27 offensive snaps in place of Jefferson during Sunday's win over the Raiders, recording four tackles (three solo) during that time. If Clark is indeed thrust into the starting lineup in Week 13, he'll work to contain Matt Ryan and the Falcons.
