Reds fans were collectively shaking their head Monday when it was revealed that Joey Votto did not have an MRI until that day.

That was 16 days after he originally injured his left knee. Votto had arthroscopic surgery Tuesday to repair a torn medial meniscus in his left knee. Votto is expected to miss three to four weeks.

Trainer Paul Lessard said it's common to wait on an MRI when the player is not having symptoms.

"We thought about an MRI," Lessard said. "But he said, 'I'll be all right.' He was able to play."

While the original injury occurred June 29, Lessard said Votto aggravated the knee Sunday against St. Louis. Votto was 2-for-3 with a double and a run scored, so he ran the bases quite a bit.

"He was fine in those two games (after the break)," Lessard said. "But then he did something to it, making a stop and twisting."
