CHICAGO (CBS) — White Sox starting pitcher John Danks is being sued by a Texas man, who says his spinal cord injury happened as a result of Danks’ failure to call 911 after a fall at Danks’ home.

WBBM’s Steve Miller reports Blake Papst, a high school classmate of Danks, claims he was injured two years ago when he fell from a structure above the rooftop deck at Danks’ Chicago condo.

“They used to be friends,” Papst’s attorney, Tim Rhatigan said.

He said, as a result of the fall at Danks’ home, Papst is now a paraplegic.

“I can’t discuss too much of his medical condition, but he is in a wheelchair,” he said.

Rhatigan said Danks did not promptly call paramedics, refused to give Papst his cell phone so he could call 911, and negligently moved Papst down flights of stairs.

The lawsuit against Danks, and others, seeks unspecified damages.

Danks is in the first year of a 5-year, $65 million contract.

Danks’ lawyer said his client denies the allegations, and he’s filing a response and a counterclaim today.
