Vogelsong was struck in the face by a 92-mph fastball while batting against Rockies pitcher Jordan Lyles on May 23. The veteran right-hander was carted off the field and taken to Allegheny General Hospital, where he spent the following three days as doctors waited for the swelling to subside around his injured left eye.
Vogelsong's eye was swollen shut immediately after he was hit, but his vision quickly began to improve afterward. He was out of the hospital and back at PNC Park, sitting in the stands with his wife, Nicole, during the Pirates' 8-3 win over the D-backs on May 26.
According to head athletic trainer Todd Tomczyk, Vogelsong has been unable to perform any strenuous physical activity since the injury occurred.
"He is a pretty fast healer," Tomczyk said Wednesday. "When the decision is made to fix the fractures, there is a chance that swelling's going to increase because of any soft tissue in any type of surgery. It may get a little worse before it gets better long-term."
Vogelsong, who returned to Pittsburgh as a free agent this offseason, went 1-1 with a 3.74 ERA in 12 appearances. He was making a spot start on May 23 when Lyles' pitch struck him directly in the left eye.
