Hill took all the starter reps at practice this week, the source said. Jameis Winston will be the backup.
Winston played most of the second half in New Orleans’ 27-13 win over the San Francisco 49ers after Brees was injured Sunday.
Hill, who is used in an occasional change-of-pace role for the Saints as a run-heavy quarterback even when Brees is healthy, played seven snaps at QB during the second half.
Brees has been diagnosed with a collapsed lung and a total of five fractured ribs on both sides of his body, a source told ESPN’s Ed Werder on Wednesday.
