First-year San Francisco 49ers head coach and offensive guru Kyle Shanahan is an unfamiliar situation, off a season in which he piloted the No. 1 offense while with the Atlanta Falcons.

Now entering Week 9 as one of two teams without a win this season, Shanahan got a piece to build around when the 49ers made a deal with the New England Patriots, landing Jimmy Garoppolo, the presumed heir apparent to Tom Brady, in exchange for a second-round draft pick.

With such a quick turnover to Sunday’s game against the Arizona Cardinals after having been traded Monday, it was a lock that the 25-year-old quarterback wouldn’t play.

On Wednesday, Shanahan noted he wasn’t sure if Garoppolo would see any time in 2017, telling 49ers writer Joe Fann, “I can’t promise you that he will play this year.”
