LSU starting pitcher Cole Henry (18) takes the mound in Game 1 of the NCAA Baseball Baton Rouge Super Regional between LSU and Florida State, Saturday, June 8, 2019, at LSU's Alex Box Stadium in Baton Rouge, La.

Freshman pitcher Cole Henry left his start Saturday in the NCAA super regional because of a nerve issue, Henry's father Jeff told The Advocate on Tuesday afternoon.

Henry couldn't make a fist and his arm shook after two shutout innings, Jeff said. Henry's velocity dipped in the second inning, and LSU removed him after 41 pitches.

Doctors determined the problem came from a buildup of scar tissue around Henry's median nerve, Jeff said. The nerve, which runs from Henry's neck to his finger tips, misfired on Henry's throwing arm.

Henry was able to throw Sunday. An MRI showed no structural issues.

"He'll be 100 percent by fall practice," Jeff said.

Henry this week planned to go home to Florence, Alabama. He won't play this summer, letting the arm rest. The family will look for a doctor in Birmingham, Alabama, to treat the nerve.

The family and coach Paul Mainieri are optimistic the nerve issue can be fixed, allowing Henry to throw before he returns to LSU for the fall semester.

Henry established himself as LSU's ace this season, but elbow discomfort sidelined him the final month of the regular season. He returned for the postseason, pitching five shutout innings during the regional.

Henry went 4-2 with a 3.39 ERA and earned a spot on the Southeastern Conference All-Freshman team. He will be a draft-eligible sophomore next season.
