Nootbaar (back) felt lingering discomfort Thursday while trying to hit off a tee, Jeff Jones of the Belleville News-Democrat reports.

EDGE Analysis

The outfielder is not going to be pushed into the full range of baseball activities until he's pain free, so his injured list stint will last longer than the minimum 10 days. He was eligible to return Friday from a lower-back contusion that has sidelined him since late May. In Nootbaar's absence, Tommy Edman has emerged as the Cardinals' primary center fielder, but the return of Dylan Carlson from the IL gives St. Louis another option.
