Chiefs The San Francisco 49ers travel to face the Kansas City Chiefs in Week 3 Authentic Laken Tomlinson jersey , and their secondary has question marks at precisely the wrong time. Jaquiski Tartt is day-to-day after suffering a shoulder stinger on Sunday, and head coach Kyle Shanahan would not yet commit to who would start at cornerback opposite Richard Sherman.The team will know more about Tartt later this week, but Shanahan said on Monday that if he can’t go, Jimmie Ward could end up as an option next to Adrian Colbert. Jimmie Ward is a backup at all of the defensive back positions. Antone Exum came on in place of Tartt for the final few snaps, but Ward was not available because he had replaced Ahkello Witherspoon in the fourth quarter against the Lions. With Witherspoon’s status for Sunday up in the air, it seems a decent possibility that Ward would start in his place, and if Tartt cannot play, Exum would start at strong safety. There is one particularly good option on the open market Youth Marquise Goodwin jersey , but the team seems fine sticking with what they’ve got.With questions at strong safety and cornerback, the 49ers have to prepare for the Chiefs’ prolific passing attack. Patrick Mahomes is off to one of the best two-game starts in NFL history, and he’s benefiting from Tyreek Hill and Travis Kelce off to strong starts. The Chiefs passing attack could not be clicking at a higher rate right now, and the 49ers have a whole lot of work to do.Shanahan: Marquise Goodwin is game-time decision, Richard Sherman, Ahkello Witherspoon should play The San Francisco 49ers will run through their final practice in Santa Clara on Friday, but we likely won’t get all the answers we’re hoping for on the final injury report for Week 3 vs. the Kansas City Chiefs. Head coach Kyle Shanahan offered some updates Friday morning about wide receiver Marquise Goodwin, and cornerbacks Richard Sherman and Ahkello Witherspoon.Goodwin has been dealing with a quadricep injury he suffered early in the team’s Week 1 loss to the Minnesota Vikings. Shanahan said Goodwin still is not quite there yet in being ready http://www.49ersauthorizedshops.com/authentic-george-kittle-jersey , and he is a game-time decision. The team will have a practice in Santa Clara on Friday, and then a walkthrough in Kansas City on Saturday. They’ll assess him after the walkthrough, and then once again after pre-game warmups on Sunday. For now, Shanahan described him as 50-50.Richard Sherman was added to the injury report on Thursday with a heel injury. Shanahan described it as wear and tear and they wanted to be smart with him. However, Shanahan said Sherman will be on the practice field on Friday and expects him to play on Sunday.The same holds true for Ahkello Witherspoon, who has been limited with an ankle injury. There was no update on Jaquiski Tartt and his shoulder injury.
