Grant (undisclosed) was placed on injured reserve by the Falcons on Thursday, Terrin Waack of the Falcons' official site reports.
The wide receiver needs to reach an injury settlement with the team in order to play this season. Grant signed with Atlanta on Saturday and was competing for a return-specialist role. The veteran last saw NFL action in 2021 with Chicago and Miami, recording 11 catches for 132 yards and two touchdowns.
