The San Francisco 49ers put Deebo Samuel on injured reserve Saturday as the wide receiver continues to recover from surgery to repair a broken foot.

Samuel, the No. 36 overall selection in the 2019 NFL Draft, must miss at least the first three games of the season. He sustained a Jones fracture of his left foot while working out in mid-June.

The 49ers’ receiving corps was beset by injuries throughout the offseason — none more significant to the team than the one to Samuel, who emerged as a top option for quarterback Jimmy Garoppolo.

The 24-year-old Samuel had 57 catches for 802 yards and three touchdowns in 2019 as a rookie. He also scored three times on 14 rushing attempts.

Also Saturday, the 49ers promoted offensive lineman Hroniss Grasu and cornerback Dontae Johnson to the active roster from the practice squad.

The 49ers begin defense of their NFC championship on Sunday when they host the Arizona Cardinals.
