A second opinion on Ryan's shoulder showed a Grade 2 teres major strain, Stephen Hawkins of the St. Paul Pioneer Press reports.
The examination by prominent sports surgeon Dr. Neal ElAttrache confirmed an initial diagnosis that Ryan would likely be sidelined for the rest of the regular season. The Twins haven't ruled out his return, but manager Rocco Baldelli previously said that Ryan's recovery will take "weeks to months", giving him a very narrow window to get back on the mound.
