Okuayinonu broke his foot in practice last week and is set to have surgery to repair the issue, Matt Barrows of The Athletic reports.
Head coach Kyle Shanahan said Monday he hopes Okuayinonu can return near the end of the regular season, but it is unclear quite how long the recovery process will take. Okuayinonu previously had a plate in his foot, and the break occurred when it was stepped on during practice.
