Carlos Guillen has MRI on shoulder

According to Steve Kornakci of the MLive.com, Detroit Tigers left fielder Carlos Guillen had an MRI on his shoulder.

And the results should be known on Tuesday.

"Carlos is not throwing or hitting right now," [Tigers head athletic trainer Kevin] Rand said this morning. "He's just conditioning and running."

Although he was initially placed on the DL due to tendinitis in his Achilles, it's Guillen's shoulder (not Achilles) that is troubling him now.

In 24 games, Guillen is hitting only .200 this season with no home runs.
