As expected, the Washington Nationals put rookie pitcher Stephen Strasburg back on the 15-day disabled list Tuesday with a strained flexor tendon and there is concern in some corners of the organization that Strasburg has suffered a more serious elbow injury.

This is his first season in the majors after being the overall No. 1 pick in the 2009 draft. The Nationals aren't sure when he will pitch again. He will undergo a magnetic resonance imaging arthrogram, where dye is injected into the arm to show contrast, on Thursday. Read more: http://sports.espn.go.com/mlb/news/story?id=5493644
