The Rays recalled Allan Dykstra from Triple-A Las Vegas of the Pacific Coast League as a replacement. Dykstra will make his major league debut Wednesday night against the Baltimore Orioles.
Rays manager Kevin Cash said an MRI revealed a "hot spot" in Loney's side, but believes the team caught the injury in time, the Tampa Bay Times reported. The team is hopeful Loney will only miss 15 days' worth of games, the report said.
Last year, Loney hit .290 with nine home runs and 69 RBI. Loney had never previously been on the disabled list during his eight-year major league career.
Tampa Bay signed Loney to a one-year, $2 million contact after the 2012 season ended after the Boston Red Sox declined to re-sign him.
After a 2013 season where he hit .299, Loney signed a three-year, $21 million deal through 2016 with the Rays.
