According to David Lennon of Newsday.com, Johan Santana is expected to be sent to New York for some precautionary tests, including an MRI, and an examination by team physician David Altchek.
Lennon quotes Mets GM Omar Minaya himself as referring to these tests as "precautionary." But this is certainly something to keep an eye on.
