SAN FRANCISCO -- The Phillies regained Jay Bruce's presence in left field for exactly one game before the left fielder returned to the injured list Friday with a flexor sprain in his left (throwing) elbow.

Bruce gained his liberation from the IL on Thursday after having been sidelined by a right oblique strain since July 17. But he hurt his elbow as he made a relay throw toward the infield after fielding Mike Yastrzemski's third-inning double in Thursday's series opener against the Giants.

Bruce, said manager Gabe Kapler, "felt a little something in the elbow" as he threw. Kapler added, "At that point, he had some concerns."

To replace Bruce, the Phillies canceled optioning outfielder Adam Haseley to Triple-A Lehigh Valley. That move proved to be convenient, since Haseley had not left the San Francisco area.

Kapler termed the severity of Bruce's injury as a "Grade 1-plus" strain. Bruce, who underwent an MRI, will not be allowed to throw for two weeks and must pass a battery of tests before he'll be medically cleared to throw again.

Bruce, a three-time National League All-Star, is batting .228 with 24 home runs and 57 RBIs in 81 games overall this season. That includes hitting .250 with 10 homers and 29 RBIs in 34 games with Philadelphia.

In 24 games with Philadelphia, Haseley's batting .274 with three homers and 12 RBIs. He started in center field and batted eighth in Friday night's game against the Giants. Corey Dickerson filled the left-field vacancy created by Bruce's departure.
