"I really don't know -- when he's feeling better," Russell said. "We'll see how he comes in [Tuesday]. Make it through today, sleep and get up, and come in tomorrow."
LaRoche has been bothered by a stiff back, and after going 0-for-4 on Friday while making his career debut in the leadoff spot, he hasn't been in the lineup since. He said before Sunday's game that he's been feeling pretty good, but evidently, his back hasn't felt that good.
"I talked to him, and he's starting to feel better," Russell said. "We'll just keep going day-to-day with it."
LaRoche, who's hitting .256 with three home runs and 10 RBIs, was spotted briefly in the clubhouse before Monday's game with the Reds, but he quickly scurried away.
