LOS ANGELES -- With the club yet to announce the severity of first baseman Lance Berkman's right knee injury, Memphis Redbirds manager Pop Warner just pulled first baseman Matt Adams from the lineup in Las Vegas, a possible indication that Adams will indeed take Berkman's spot by Sunday.

Adams currently is not on the Cardinals' 40-man roster. Adding him would not be an issue as the roster stands at 38 following the release of J.C. Romero and the waive of outfielder Erik Komatsu.

LOS ANGELES -- The Cardinals just announced that Lance Berkman has sustained a right knee injury. The club did not specify the nature of the injury, only that he would be re-evaluated Sunday.

Berkman required reconstructive surgery on his right anterior cruciate ligament in November 2004. That injury required a five-month rehab before he was activated on May 6, 2005. The club has not disclosed whether tonight's injury affects the same area of his knee. No stranger to leg issues, Berkman seemed to immediately recognize something was seriously wrong after accepting a throw from shortstop Rafael Furcal.
