The New Orleans Saints placed quarterback Drew Brees on injured reserve on Friday, guaranteeing the NFL’s all-time leading passer will miss at least the next three games.

Brees suffered rib fractures on each side of his chest and a collapsed right lung last weekend, seemingly when he took a crushing hit from San Francisco 49ers defensive lineman Kentavius Street in the second quarter of New Orleans’ 27-13 win.

Brees remained in the game and threw a touchdown pass before half-time but remained on the sidelines for the second half.

Scans on Monday revealed his injuries, which kept him out of practice even before he was placed on injured reserve.

The 7-2 Saints, winners of their past six games, enter Sunday’s contest against the Atlanta Falcons tied for the best record in the NFC and with a half-game lead over the Tampa Bay Buccaneers in the NFC South.

Earlier on Friday, multiple media outlets reported that Taysom Hill – not Jameis Winston – will be the Saints’ starting quarterback this week.

The Saints have yet to put a timetable on Brees’ recovery, but he is guaranteed to miss two games against the Falcons and a game against the Broncos in Denver. Brees will be eligible to return on December 13 against the Philadelphia Eagles.

Brees remains 388 passing yards short of becoming the first player to ever throw for 80,000 yards in an NFL career.
