Luebke, who had surgery in May 2012, threw four bullpen sessions in the last month. The first two went well, but he experienced soreness in the elbow recently.
"We're going to back him off throwing for a while," Padres manager Bud Black said after a 4-0 victory over the Braves on Sunday.
When asked if Luebke would be fine to throw at the start of Spring Training in five months, Black said that it was "way too early to tell."
"That's a lot of time to heal," Black said. "That's what we're hoping for."
Luebke has experienced a handful of stops and starts during his rehabilitation program in the last six months. There was a possibility that he would get some innings during winter ball, though that seems remote at this point.
