MINNEAPOLIS (WCCO) – For the second time since he was released from rehab, high school hockey player Jack Jablonski has returned to the hospital.

The Benilde-St. Margaret’s student was released from Sister Kenny Institute in April, and returned to the hospital a week later after suffering “issues that are common to people with spinal cord injuries.”

Jablonski was injured after he was checked from behind during a hockey game on Dec. 30, 2011.

Jablonski’s parents wrote on his CaringBridge page that the sophomore has been up and down in the last month, and returned to Sister Kenny Institute after he started feeling ill again.

“We’re waiting for test results and hoping that his docs are able to figure out a plan to prevent these frequent mishaps from sending us to the ER every few weeks,” said the CaringBridge post on Monday.

Last time Jablonski returned to the hospital, his parents said it was particularly difficult because he had been scheduled to throw out the first pitch in a Twins game at Target Field with his brother Max.

Jablonski spent a total of 111 days in a hospital bed before his first discharge from Sister Kenny Institute.
