The Cardinals sent right-handed starter Kyle Lohse back to St. Louis on Thursday to have a finger on his pitching hand examined by the team's doctor, Derrick Goold of the St. Louis Post-Dispatch writes.
The Cardinals have already been rumored to be searching for starting pitching, and any kind of injury to Lohse would magnify that need. It could also affect the bullpen, as any starter added to the rotation was expected to bump Kyle McClellan back to the bullpen.
Manager Tony La Russa wouldn't give many specifics about Lohse.
"He's still scheduled to be our guy Sunday," La Russa told Goold. "We'll keep our fingers crossed."
Lohse, 32, is 8-7 with a 3.45 ERA in 19 starts this season, but he has struggled in July, going 0-3 with a 7.64 ERA in three starts. He's 1-5 with a 5.70 ERA since the start of June.For more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
