Detroit – Shane Greene's season is likely over.
He has been diagnosed with a pseudoaneurysm in his right hand and will see a vascular specialist in Dallas on Tuesday.
"He has an arterial issue in the shoulder, some weakening of the blood vessels," Tigers head athletic trainer Kevin Rand said. "It affects his blood flow to his middle finger. The middle finger was the main issue and there's some question about the index finger, too.
"It's something we just have to take a good, hard look at."
Rand said Greene felt his middle finger go cold before his last scheduled start in Toledo.
"We thought it had to do with the major blister he had on the same finger, but it was a little deeper than that," he said.
Rand said this issue is unrelated to the ulnar neuritis that had bothered him earlier this season.
"It's not technically an aneurysm but it functions like an aneurysm," he said. "The artery is compromised in the shoulder and it affects the hand."
A decision on whether surgery will be required will be made Tuesday after he is examined by Dr. Greg Pearl in Dallas. He's worked on former Tigers pitchers Jeremy Bonderman and Kenny Rogers.
Rand didn't want to speculate on whether Greene's season was over until after Tuesday's exam, but manager Brad Ausmus isn't optimistic.
Asked if Greene's season was likely over, he said, "More than likely."
Greene, acquired from the Yankees in a three-team trade for Robbie Ray and Domingo Leyba, began the season as the team's No. 5 starter. He won his first three starts, allowing one earned run, but things unraveled quickly.
He wound up with a 4-8 record and a 6.88 ERA and 1.554 WHIP. He was on his second stint in Triple-A when the injury occurred.
