Via Tom H.:

Butler said he continues to be bothered by soreness in his triceps and had to stop throwing (during a bullpen session yesterday). He will be examined by a doctor later today. If it turns out to be triceps tendinitis, he'll probably be shut down for awhile.

And on Oeltjen:

I also spoke with outfield candidate Trent Oeltjen, who was struck above his left wrist by a pitch in the Brewers' exhibition game Friday vs. Oakland. He has a splint on the wrist, which he said is "just for protection." He's scheduled to go for X-rays in a little while and be seen by a doctor, so we'll know the extent of the injury later.
