Winker exited Friday's win over the Cubs due to back tightness, Bobby Nightengale of The Cincinnati Enquirer reports.

EDGE Analysis

Winker was replaced by Mark Payton in left field to begin the seventh inning, and manager David Bell revealed after the game that the 27-year-old was dealing with a back issue. However, Bell was hopeful that Winker would be back in the lineup for Saturday's game against the Cubs.
