49ers place defensive end Sam Okuayinonu on injured reserve with foot injury

The San Francisco 49ers added defensive end Sam Okuayinonu to the injured reserve list on Monday after the veteran suffered a broken right foot. Coach Kyle Shanahan confirmed Okuayinonu requires surgery following an injury sustained during a final bonus practice session last week. The loss of Okuayinonu creates an immediate vacancy on the defensive line depth chart as the team prepares for the upcoming season. The unit already faces uncertainty with Nick Bosa working back from a major injury and first-round pick Mykel Williams currently sidelined on the physically unable to perform list. The team has signed Khalid Kareem to the roster to provide depth in the interim. Rookie Romello Height and Keion White are expected to take on larger workloads while the team manages multiple injuries across the defensive front.
