The San Francisco 49ers have opened a 21-day practice window for veteran receiver Christian Kirk, who has been sidelined since injuring his calf on the first day of training camp. This move provides the team with a potential internal solution to their depleted receiver corps, which has been affected by multiple injuries, including Ricky Pearsall's season-ending injury and Deebo Samuel's hamstring strain.

Despite the ongoing challenges, the 49ers have not pursued immediate trades for additional receivers, as evidenced by their recent workouts focusing on linebackers instead. Head coach Kyle Shanahan expressed confidence in the current roster, stating, “I think we have enough.” While the situation could change if injuries persist, the team appears committed to evaluating Kirk's return and the ensuing competition among their remaining receivers before considering external options.
