The Giants announced that Johnson suffered a torn Achilles' tendon during Wednesday's practice.
Per Jordan Raanan of ESPN.com, Johnson was vying for a possible key role at wideout after a strong training camp, which included catching 10 passes for 123 yards across two preseason games. However, the 2020 fifth-round pick's season is now likely over before it started, and he could be in danger of missing the start of the 2023 campaign as well.
