"The healing process, the time doesn't change," Girardi said. "In four weeks, he'll start doing rehab."
Granderson has missed 43 of the Yankees' 51 games this season. He sat out the first six weeks of the season after fracturing his right forearm during Spring Training. In eight games with the team, he batted .250 with one home run and one RBI while striking out six times over 28 at-bats.
Granderson is still expected to be sidelined a minimum of four weeks.
"It's basically four weeks of inactivity, then you go from there," Girardi said. "You can't expect him to go four weeks of inactivity and be in a game the next day."
