Teixeira said he does not have a set timetable, and he is taking it day by day during his rehab.
"With a muscle strain, you got to let them heal [on their own]," he said. "I'm going to make sure it's healed [before I return].
"I've been doing a lot of pool work and taking it easy. I've been sleeping a lot -- it's the quickest way to heal."
When he went on the DL, Teixeira's franchise record of playing in 507 consecutive games came to an end.
"It's tough, but it's part of the game," he said. "It's just a bump in the road. I got to deal with it and keep up [rehab]."
Starter Brandon McCarthy, who went on the DL on June 14, will go on a rehab assignment before rejoining the team.
"The purpose of putting him on the disabled list was to make sure he would come back 100 percent, and we were confident the blister was a thing of the past," Daniels said. "We want to make sure he tests it before he comes back."
The rehab assignment means a couple more starts for Kameron Loe, who was recalled from Triple-A Oklahoma when McCarthy went on the DL.
Sosa milestone: Sammy Sosa was one home run shy of becoming the fifth Major League player to reach the 600 mark, heading into Tuesday's game against the Cubs. Chicago manager Lou Piniella said reaching that number is a lock for the Hall of Fame.
"I'm not in position [to say anything] for that, but 600 is 600," Sosa said. "But, somebody else has to make that call."
Sosa said the Rangers will celebrate his 600th blast, but it will be far from his last.
"I can play five more years," Sosa said with an impish grin.
Owner Tom Hicks announced earlier Tuesday that Daniels received a one-year contract extension through 2009. Shortstop Michael Young said he was in favor of the extension.
"As far as wins and losses go [this season], it's unacceptable," he said. "I don't want to rebuild, we need to fix it immediately. ... But, we definitely need stability, that's been an issue the last few years."
Young said that turning the team around will not be easy, but it's what he expects.
Washington, who was hired by Daniels, was pleased as well.
"Jon Daniels is one of the best people I've met in baseball, not because he hired me, but because of who he is," he said. "It shows [Hicks] believes he's going in the right direction."
He said it:
"I don't have any response to that. I don't want to talk about anything off the field." -- Teixeira, on Daniels' one-year contract extension
