Stauffer, on the disabled list for the second time this season with a strained right elbow, is headed for what his manager called "lengthy rest."
"We're looking at more extensive rest for Tim," Padres manager Bud Black said. "Even when he's eligible to come off the disabled list, he's going to need more time."
Stauffer started the season on the disabled list and then returned to make a start on May 14 against Washington. He said he experienced soreness in his elbow -- in his flexor tendon bundle -- late in that outing. He allowed four runs (three earned) in five innings against the Nationals.
Stauffer went back on the disabled list on May 18, retroactive to May 15.
Stauffer recently had a second opinion on his elbow by noted orthopedist Dr. Lewis Yocum, who also repaired pitcher Cory Luebke's damaged left ulnar collateral ligament last week.
The Padres currently have four starting pitchers on the disabled list -- Stauffer, Luebke, Joe Wieland and Dustin Moseley. Luebke and Moseley are out for the rest of the season.
