Coach Jim Harbaugh brought his team together less than an hour into practice Wednesday evening and abruptly led his team out of Levi's Stadium due to poor field conditions.

Basic plays provided huge divots, and there were patches of sod that were still discolored from the 49ers' game Sunday against the Denver Broncos.

General manager Trent Baalke, standing on the sideline, was clearly agitated by uneven turf, which has yet to take root. And when wide receiver Stevie Johnson fell hard after slipping on a simple out-pattern during a 7-on-7 drill, Harbaugh brought his team together near midfield to play it safe.
