Rangers starter Matt Harrison underwent surgery in mid-April to correct a herniated disk in his back. The left-hander felt fine for the first eight days of his rehab but suddenly began experiencing discomfort in both of his legs one week ago and required a second back procedure on Wednesday afternoon.
This according to Anthony Andro, the Rangers beat writer for FOXSportsSouthwest.com.
Harrison was ruled until after the All-Star break following his first back procedure and might now struggle to return before August. The 27-year-old had an ugly 8.44 ERA, 1.97 WHIP and 12/7 K/BB ratio in 10 2/3 innings this season before going down.
