"That's been delayed because of how he's felt from the flu, but he's starting to feel better." Farrell said. "The flu symptoms are slowing. We are still trying to keep him away from everyone else for obvious reasons."
Victorino was at Fenway Park on Friday to celebrate the Red Sox 2013 World Series championship and collect his ring.
Farrell expects to get a better idea of how Victorino is feeling physically near the end of the week. After that, he'll decide what the right fielder's next step will be.
"Come the end of the week, we'll likely start to ramp things up more," Farrell said. "We'll get a better read on a projected time for a rehab assignment."
