Eyre was not an immediate candidate for the disabled list. The Cubs want to see how he responds to treatment first. However, he was not expected to be available Friday for the start of the Interleague series against the White Sox.
Eyre started the sixth against the Baltimore Orioles, and got Alex Cintron to ground out. He walked Nick Markakis, and pitching coach Larry Rothschild and athletic trainer Mark O'Neal went to the mound to check on the lefty. Kevin Millar then singled, and Rothschild, O'Neal and Cubs manager Lou Piniella all went to the mound, and Eyre was pulled.
Both Markakis and Millar scored later in the inning, and the Orioles posted an 11-4 victory.
Eyre began the season on the disabled list because of a bone spur in his left elbow. The Cubs have had to deal with a sudden rash of injuries. Alfonso Soriano is sidelined with a broken bone in his left hand, Carlos Zambrano is on the disabled list because of a strained right shoulder, Reed Johnson was on the DL with back spasms, and Kosuke Fukudome did not start because of a sore left calf.
