The Atlanta Falcons announced Saturday that second-year running back Ito Smith is being placed on injured reserve. In a corresponding move, the Falcons have signed offensive lineman Sean Harlow from the practice squad to the active roster.

Smith, 24, entered the season as the No. 2 running back on the depth chart behind Devonta Freeman and carried the ball 22 times for 106 yards with a touchdown. He sustained a concussion against the Los Angeles Rams that has sidelined him since. With Smith heading to IR, Brian Hill figures to be the second-string running back moving forward.

Harlow, 24, was drafted by the Falcons in the fourth round of the 2017 NFL Draft and has spent his time in Atlanta on the team's practice squad. The move comes one day after the Falcons declared reserve offensive lineman Wes Schweitzer out for Sunday's game due to a concussion.
