After the game, the Brewers made a roster move.
This move isn't a surprise, as the strain looked back when Henderson tried to pitch with it yesterday. The Brewers may have caught a break with the injury, as it looked like it was a lot worse yesterday. Considering how much it impacted his ability to pitch, the Brewers will probably make sure Henderson is 100% before bringing him back.
The Brewers did not make a corresponding move right away, and will wait until tomorrow to make an announcement. The move may be for a starter rather than a reliever, as the Brewers had to use their planned starter for Tuesday, Alfredo Figaro, in relief on Saturday. There is a lot to consider here and we will have to wait and see what the Brewers decide.
