Fielder had neck surgery on May 27, 2014, and missed the rest of the season. This herniation is just above the previous injury.
The Rangers also put outfielder Shin-Soo Choo on the disabled list with inflammation in his lower back. He had an anti-inflammatory injection and is expected to miss 10-14 days.
The Rangers called up infielder Hanser Alberto and outfielder Delino DeShields to replace them. Jurickson Profar will likely get more playing time with Fielder out.
T.R. Sullivan has covered the Rangers since 1989, and for MLB.
