For the second time this offseason, a Baltimore Orioles free-agent signing is in jeopardy over issues related to a physical exam.
A deal with outfielder Tyler Colvin, who reached agreement with the Orioles on a one-year contract last week, is on hold because the team has issues with his physical, a baseball source told ESPN.com.
In December the Orioles made news when they backed out of a two-year, $15 million deal with free agent closer Grant Balfour, reportedly over concerns about his wrist and knee. Balfour went back on the market and is still looking for a home.
Colvin suffered a collapsed lung in 2010 when he was struck in the chest by a piece of a broken bat, and last season he was bothered by a disc problem in his back. But a source said the outfielder has been working out regularly five days a week in Arizona this winter.
