UPDATE: the tribune is now reporting:
Cubs general manager Jim Hendry confirmed Prior was removed from the game against minor league hitters, but declined to comment on the injury without having all the details.
WSCR-AM 670 was reporting Thursday that Prior left with soreness in his side. He was disabled last summer with a strained oblique muscle.
UPDATE: it's a sore shoulder.
The Cubs announced Thursday afternoon that Prior would be examined by Dr. Lewis Yocum, an orthopedic specialist, within the next few days.
Prior experienced discomfort in his right shoulder in the second inning. He left after completing the inning.
Prior was disabled twice with shoulder soreness last season.
this writer, for one, is surprised he gutted it out and hid it for that long. he must believe his career is over at this point.
