Whether Gennett plays in the Minors beyond Tuesday remains to be seen.
"I just think we'll wait and see how many games he'll play," manager Craig Counsell said.
Gennett had multiple hits in three of the six games he played before he got hurt. He is batting .258 this season with a .361 on-base percentage, which would set a career high. He already has 10 walks in 72 plate appearances, two shy of his total last season in 391 plate appearances.
