CHICAGO -- Chicago Cubs All-Star first baseman Anthony Rizzo remains out of the lineup with lower back tightness and could get an MRI if the ailment continues.

“Still day-to-day,” manager Rick Renteria said before Monday’s game against the Milwaukee Brewers. “Still a little stiff. If it doesn’t clear up maybe we’ll get an MRI just to make sure everything is ok. But he’s doing fine. We’re just limiting him, just making sure once he gets back on the field, he doesn’t have a setback.”

Rizzo has missed the last seven games, including Monday’s affair, after leaving a game in Cincinnati last week. He tweaked his back on a swing and immediately came out of the contest. Rizzo is hitting .278 with a career high 30 home runs to go along with 71 RBIs.

With rosters expanding for the month of September, the Cubs recalled right handed pitcher Blake Parker. Manager Rick Renteria said a “half-dozen or so” others could be called up after Triple-A Iowa’s season ends Monday.
