The Rangers are expected to place Jung (wrist) on the 10-day injured list, ending his season, Evan Grant of The Dallas Morning News reports.
Jung hasn't played since last Wednesday due to recurring discomfort in his surgically repaired right wrist. He is scheduled to be seen by a hand specialist Thursday in hopes of getting more information on the injury. Ezequiel Duran has started three of the last four games at third base and should continue to be the primary option at the position in the final week of the season. The Rangers are expected to promote either Dustin Harris or Sam Huff from the minors to take Jung's spot on the 28-man active roster.
