DENVER -- Nationals catcher Ivan Rodriguez has experienced a setback in his recovery from a strained right oblique and will not begin a Minor League rehab assignment over the weekend, manager Davey Johnson said on Thursday.
Rodriguez will visit Dr. Bill Meyers in Philadelphia for a second opinion. Meyers is the same doctor who performed surgery on Ryan Zimmerman's torn abdominal muscle in May.
It is not yet known whether Rodriguez's injury will require surgery.
"They just want another opinion," Johnson said.
Rodriguez, who has been on the disabled list since July 7, was expected start a rehab assignment over the weekend with Class A Hagerstown, but that has been scratched for now.
"I know how anxious Pudge is to get back out here," Johnson said. "I'm sure he's been pushing it, and I'm sure he's been aggravating [his injury] by pushing it."
In 39 games as a backup catcher, Rodriguez is hitting .214 with two home runs and 19 RBIs.
