NFL replay assist is expected to expand this offseason into plays that could include the quarterback slide, league sources told ESPN on Saturday. The NFL enacted replay assist in 2021 to allow replay officials and designated members of the officiating department to assist with on-field calls in limited game situations.

Back in 2021, the NFL implemented replay assist with the goal of improving on-field referee accuracy. At the time, its scope was limited to ball placement and pass completions. However, by 2023, it had broadened to include penalties such as blows to quarterbacks’ heads and intentional grounding.
