Hellickson has been in camp all spring rehabilitating. Thursday will be a significant day for him, as he'll actually throw a baseball for the first time since his surgery.
Hellickson said he will play catch with Ron Porterfield, the Rays' head athletic trainer, for approximately five minutes from distances ranging from 45-60 feet.
"I feel good," said Hellickson, who noted that he expected all to go well.
