Fortes is out of the lineup for Tuesday's game against the Reds due to quadriceps tightness but will be available off the bench, Kevin Barral of FishonFirst.com reports.
Fortes departed Monday's contest due to the injury and was limited to running at 75 percent Tuesday. It remains to be seen if a stint on the injured list will be necessary. Ali Sanchez is working behind the plate and batting ninth.
