Brett Lawrie suffered another setback this week and has been pulled from his rehab assignment, according to the White Sox.
The White Sox second baseman will be re-evaluated on Monday and the team hopes to have more information this week.
"He's coming back and we'll re-evaluate. He couldn't get through last night," White Sox manager Robin Ventura said. "As we talked about today before the game, we need to get him back here and take a look at him."
Lawrie has been on the disabled list since July 22 with a strained left hamstring.
He began his rehab assignment last weekend, but exited Thursday's game with a sore quad. On Saturday, he was held to four innings and had to be removed from that contest as well.
“For us, he’s going to have to play a full game to be able to get back here and know you’re going to play,” Ventura said. “You’re going to have to be able to get through it a few times to feel like you can come back up here and get off the DL."
In Birmingham, he played in five games and went 5-for-16 with two runs and a double.
