49ers fear WR Brandon Aiyuk tore right ACL in loss to Chiefs
On a day when the San Francisco 49ers celebrated the return of one wide receiver, they lost another -- possibly for the season.
Brandon Aiyuk, who has led the Niners in most receiving categories in the past two seasons, suffered what the team fears is a torn anterior cruciate ligament in his right knee in Sunday's 28-18 loss to the Kansas City Chiefs.
If the further testing Aiyuk has coming in the next 24 hours confirms that diagnosis, Aiyuk will need surgery and miss the rest of the season.
"That's what it looks like, but we don't know for sure," coach Kyle Shanahan said. "Been wrong before. So, praying that we are."
At the start of the day, Aiyuk was the only healthy 49er among the team's top three wideouts. Jauan Jennings was ruled out Friday with a hip injury, while Deebo Samuel arrived at Levi's Stadium with an illness that was announced about 30 minutes before the game with the caveat that Samuel was expected to play.
