"Ninety-nine times out of 100 a player would seek a second opinion on this," Mozeliak told the St. Louis Post-Dispatch. "At this point, Adam would like to seek a second opinion, so before we make any conclusions on what was found we're going to do that at this time."
Wainwright met with team doctor Dr. George Paletta in St. Louis on Wednesday afternoon and there was no change to the Cardinals' stance that it is a "significant" injury.
Wainwright's MRI and other information is being forwarded to Dr. Lewis Yocum in Los Angeles.
Still, whatever happens, it doesn't look good. Mozeliak wouldn't say Wainwright would need season-ending ulnar collateral ligament surgery (better known as Tommy John surgery), but he said everything but.
"I don't want to speculate, but obviously ligament damage, that's usually what it results in," he told the Associated Press.
Wainwright has finished in the top three of Cy Young voting in each of the last two seasons, going 20-11 with a 2.42 ERA last season, good for a runner-up finish to Roy Halladay.
Wainwright's elbow was examined after the season, but it was determined at the time he didn't need surgery. On Monday, Wainwright said he felt something wrong in his elbow. Cardinals manager Tony La Russa said he didn't feel the injury was associated with last season's injury, which kept Wainwright from finishing the season.
"It was so strange because he had a great throw his first time out," La Russa told the AP.
