Carroll made his comments in an interview with 710 ESPN Seattle, during which he also said the team and Marshawn Lynch have been in active talks about the running back's future with the team.
Carroll said he "might have been misled" when he said Monday that Sherman would require Tommy John surgery, an elbow-ligament-replacement procedure named after the former Major League Baseball pitcher.
"He's not a pitcher, and he's not a left-hander. Sherm might not have to have that kind of surgery," he said. "If he was a thrower he would."
Carroll didn't clarify what type of procedure Sherman would undergo if he doesn't have the Tommy John surgery.
Sherman hurt his elbow during the second half of Seattle's 28-22 overtime win over the Packers in the NFC title game on Jan. 18.
