Manager Bobby Valentine tells the Boston Herald that no roster move is expected "for now," but of course a trip to the DL remains a possibility for Beckett. Still, Valentine classifies the injury as "nothing serious." Left-hander Franklin Morales will start Sunday in Beckett's stead.
On the season, Beckett has a 4.14 ERA in 78.1 innings. Morales has a 3.04 ERA, but he hasn't made a start since 2009, when he was with the Rockies.
