Gallen is questionable for Opening Day after dealing with shoulder issues this offseason, Nick Piecoro of The Arizona Republic reports. He is scheduled to throw off the mound in the coming days, per manager Torey Lovullo.
Lovullo said Gallen underwent an MRI on his own during the lockout and was diagnosed with bursitis (inflammation). We shouldn't assume he will throw off a mound in the coming days until it actually happens, and he's got almost no margin for error at this point to get built up for Opening Day.
