Cardinals manager Mike Matheny said the slugger would be available to pinch-hit if necessary.
"When he came in, he was not where he thought he would be," Matheny said before Thursday's game. "Check back tomorrow."
Beltran missed his fourth start as a result of the problematic knee. There has been no talk about him possibly going on the disabled list, and he popped out as a pinch-hitter in the ninth inning Thursday.
"You never know, but I was hoping to write him in today," Matheny said. "It didn't work out."
Beltran is hitting .293 with 13 home runs and 32 runs driven in.
