Wainwright (back) will throw a bullpen session at Busch Stadium on Monday, the team's official site reports.

EDGE Analysis

The Cardinals have let Wainwright know that he'd have to throw a pain-free side session off a mound before they'd consider activating him from the 10-day disabled list. As such, the veteran right-hander will attempt to accomplish the feat during the Cardinals' off day, although manager Mike Matheny is still having Luke Weaver prepare as if he'll be the Wednesday starter against the Brewers for the time being.
