Broxton's elbow bothered him during the week. He had an ultrasound on Friday that found swelling in the elbow. Manager Dusty Baker said the problem doesn't appear to be serious.
"Actually, it turned out better than it could have," Baker said. "There's no structural damage, no ligament damage. That's a big plus.
This will give it time to clear up. He could be throwing in two or three days, so it's not too bad of a situation. He could be ready to go when his time is up."
Broxton pitched the 14th inning and took the loss in a 6-5 defeat at Wrigley Field on Thursday. Baker was trying not to use him, but the long game forced his hand.
"They assured us in the beginning that we couldn't make it worse by pitching," Baker said. "If it had been structural, we would've put him on the DL right away. If anything, we're overly cautious, especially at this time of year. If it was September, it might be a different story."
