Bad news follows the New York Giants' 0-3 start.
Martinez's injury happened in the first quarter during the Falcons' first possession of the game. Attempting to tackle Cordarrelle Patterson, Martinez fell to the ground without contact along the Falcons sideline. Martinez was helped off the field and went to the Giants locker room under his own power before being ruled out by the team shortly thereafter.
The Giants defense will certainly feel the loss of their defensive play-caller and captain. Martinez, 27, led the team in tackles (151) in his first season with New York after signing a free-agent deal before the 2020 season. The sixth-year pro has registered at least 144 tackles in each of the past four seasons and was leading the team in tackles (21) through the Giants first two games.
As for notable injuries sustained on the offense, coach Joe Judge said Monday the team is still awaiting doctors' reports on the hamstring injuries to receivers Sterling Shepherd and Darius Slayton.
"Those are two key parts of our offense we don't want to be without," he said, per SNY.

Bernard's status for Week 4 is to be determined. The team also activated linebacker Kevin Minter has been activated from the reserve/COVID-19 list.
- New Orleans Saints left tackle Terron Armstead is expected to miss several weeks with an elbow injury suffered in Sunday's win over the Patriots, Rapoport reported.

Tests are ongoing, but Norman is in good spirits and hopes to play next week, Rapoport added.

- The Baltimore Ravens placed rookie linebacker Daelin Hayes on injured reserve.
- Los Angeles Rams linebacker Justin Hollins is set to undergo surgery on Tuesday to repair his partially-torn pec muscle, per coach Sean McVay.
