HOUSTON -- Center fielder Brett Jackson, out since Friday after he bruised his right knee crashing into the outfield wall in Pittsburgh, could be back in the Cubs' lineup as early as Tuesday.
Manager Dale Sveum said the team would monitor how Jackson swung the bat before Monday's game. With left-hander Dallas Keuchel on the mound on Monday, Jackson wasn't likely to start even if fully healthy. The 24-year-old has made three starts against left-handed pitching since coming up from Triple-A Iowa on Aug. 5.
Right-hander Jordan Lyles gets the ball for the Astros on Tuesday, a more likely situation for Jackson to make the lineup.
"We'll probably get him out early and see if he can go tomorrow," Sveum said.
Jackson, the Cubs' No. 3 overall prospect has appeared in 31 games and made 29 starts in center field for the Cubs, entering Monday's game. He was batting .191 with a .404 slugging percentage in 94 at-bats.
Joe Mather has started the last two games in center field.
