Kittle (undisclosed) is still dealing with an injury from training camp and won't resume practicing until next week, Nick Wagoner of ESPN.com reports.
Kittle played a few drives in the Niners' final preseason game after missing some practices with a groin injury. He's still not quite 100 percent though perhaps healthy enough to play, so the team wants him to take this week off before returning to the field Monday as a full participant. The 49ers' first official injury report of the season won't be released until next Wednesday, four days before the team's Week 1 road matchup with Pittsburgh.
