Wilhelmsen, who is currently on the 15-day DL with the injury, doesn't have any structural damage and is waiting for the dye from the MRI to clear out of his system and the pain to go away before resuming throwing.
"I'm feeling loads better," Wilhelmsen said. "All the fluid from the MRI is finally out of my arm. I was expecting to throw about a week after it happened, but they put the ink in there, and that lingers. Today is the first day where I haven't had any aches or anything due to it."
He is hoping to throw Friday.
"Structurally, everything is strong and secure, and I'm good to go," he said. "The plan now is to throw maybe Friday."
He has not allowed a hit or a walk in his past five appearances.
