Detroit Tigers outfielder Riley Greene has a stress fracture in his left fibula and is out indefinitely, the team announced Wednesday.
Greene will receive a second medical opinion on the injury before the Tigers determine a timetable for his return. The injury was revealed Tuesday night when the second-year star underwent medical tests after an early exit against the Texas Rangers.
The Tigers placed Green on the 10-day injured list before Wednesday's game against the Rangers and selected the contract of outfielder Jake Marisnick from Triple-A Toledo in a corresponding roster move. Right-hander Trey Wingenter was transferred to the 60-day IL to make room for Marisnick on Detroit's 40-man roster.
"Obviously, there's going to be a rest period of at least 10 days," Tigers manager A.J. Hinch said. "For me to speculate what it means beyond that is just guessing."
Greene left Tuesday's loss to the Rangers in the third inning after reporting discomfort in his left leg. Hinch said he "needed to get him out of the game" after watching Greene run after a fly ball in center field.
Greene, 22, is batting .296 with five home runs and 18 RBIs with a team-leading 60 hits and 29 runs scored. The former No. 5 draft pick is the latest high-profile player sidelined for the Tigers, who also placed ace left-hander Eduardo Rodriguez on the 15-day IL on Tuesday with a finger injury.
"I think we have to admit that it's really frustrating," Hinch said. "It's hard on a team. And at the same time, we have to collect ourselves and go out and figure out a different way."
The Tigers (26-28) have recovered from a 2-9 start to the season and, with Wednesday's 3-2 victory over Texas, moved just 1.5 games behind the first-place Minnesota Twins (28-27) in the AL Central.
