Mitch Wishnowsky (back) missed a second practice this week, and newly signed punter Pat O’Donnell was on the field working with long snapper Taybor Pepper during practice. The 10-year NFL veteran could get called up from the practice squad on Sunday if Wishnowsky is unable to punt.

Kyle Shanahan said the 49ers are being smart with George Kittle, and cited Nick Bosa practicing through injury last week.
