9/8 Jackson day to day

Brett Jackson was walking gingerly on Saturday, one day after his head-first collision with the outfield wall at PNC Park. Somehow, the Cubs rookie outfielder suffered only a bruised knee and some scratches. There’s no timetable for Jackson’s return.

“It’s very day to day-ish right now,” Dale Sveum said. “He’s obviously pretty sore and pretty bruised up.”

Jackson said his style is to play without fear as he roams center field.

“That’s the kind of player you want but there does come the risk factor of injury when you do that,” Sveum said. “That’s why, with the last couple years with Carlos Gomez playing like that in Milwaukee, they’re bound to get hurt. The speed they create and the running, whether it’s diving on the bases when they’re running, and the fearlessness they have of walls, sometimes it’s just a matter of time before something happens.

“You don’t take that away from anybody — it’s a gift and a good thing,” Sveum said. “If he doesn’t catch that ball last night, it’s a whole ‘nother ballgame.”
