In a corresponding roster move, Houston called up outfielder Alex Presley from Triple-A Fresno.
He stayed in the game but was removed in the next inning and sent for X-rays. No surgery is planned for now and Springer will be examined again in two weeks.
"We're going to allow the bone—the particular bone, it's a non-displaced fracture—we're going to allow it heal on its own," Astros general manager Jeff Luhnow said. "We'll do whatever we can to speed that up, but nature has to take its course, so it's hard to tell [how long he'll be sidelined]."
Luhnow said the earliest that Springer would return is in six weeks, if he is cleared resume baseball activities.
Springer, 25, is batting .264 with 13 homers, 29 RBIs and 14 steals in 75 games for the Astros this season.
Houston (47-34) has the best record in the American League and a five game lead in the American League West over the Los Angeles Angels.
