Cardinals' Keynan Middleton: Might be back this weekend

Middleton (forearm) will be evaluated for potential activation from the injured list following back-to-back rehab appearances with Double-A Springfield on Wednesday and Thursday, Jeff Jones of the Belleville News-Democrat reports.

Middleton hasn't allowed a hit or a run in two scoreless rehab innings so far, although he's also walked three and has not recorded a strikeout. He's been out all season with a right forearm strain.
