Lasco went down after tackling Bills returner Brandon Tate while covering a kickoff early in the second half.
The second-year running back was taken off the field in an ambulance and transported to a local hospital, where he had movement in his extremities.
Coach Sean Payton said after the game that “all signs are positive” for Lasco.
Another good sign for surrounds Lasco flying back with the team to New Orleans, and he will undergo further evaluation Monday.
