Cardinals' pitcher Jason Isringhausen has been in a knee brace rather than on the disabled list, according to St. Louis Post-Dispatch. Isringhausen, who felt "a pop" in the knee while stretching between innings of his last appearance, admitted the condition remains painful but insisted he could pitch with any discomfort. "It?s my understanding that there?s not much risk of that happening," Isringhausen said Saturday. An MRI performed Friday revealed a strain of ligament, tendon, and the capsule on the outside of Isringhausen?s right knee.
