Cubs' Kyle Hendricks: Throwing off mound this weekend

Hendricks (back) will throw a bullpen session this weekend in Boston, Bruce Levine of 670TheScore.com reports.

The Cubs will map out a plan for Hendricks' rehab based on how he feels during and after the bullpen session. Hendricks was placed on the 15-day injured list Tuesday with a lower-back strain. Given his 12.00 ERA in five starts this season, the team might elect to give him ample time on a rehab assignment with the hope that he can get back on track upon returning from the IL.
