St. Louis Cardinals catcher Yadier Molina left the second game of Tuesday's doubleheader against the Pittsburgh Pirates with a right knee sprain and will return to St. Louis Wednesday for further evaluation, the team announced.

The five-time All-Star was replaced in the lineup by Rob Johnson after going 0 for 2 in the second game. He also had a passed ball defensively that allowed a runner to score from third.

Molina has been dealing with pain in the knee since last month and had a MRI earlier this month that showed that he had inflammation in the knee. The Cardinals are struggling, having lost six games in a row, and have lost their lead in the National League Central to the Pirates.

Molina is third in the National League in batting average, hitting .331 in 98 games, to go along with eight home runs and 54 RBI this season.
