Cardinals manager Oliver Marmol said Wednesday that the team is hopeful Herrera (knee) can begin a running and catching program this weekend, John Denton of MLB.com reports.

EDGE Analysis

Herrera has progressed to hitting in the batting cage and playing catch and could take another step forward in his rehab this weekend. If that happens, the club will have a better idea on a timetable for his return. When the Cardinals announced last week that Herrera had been diagnosed with a bone bruise in his left knee, he was estimated to be facing a four-week recovery timeline.
