Marlins' Miguel Rojas: Undergoes MRI on finger

Rojas underwent an MRI on his left index finger Thursday and could require surgery, Christina De Nicola of MLB.com reports.

Rojas signed a two-year, $10 million extension earlier in the week, but the news isn't all positive about the veteran shortstop. It's not yet clear exactly what's wrong with his finger, nor is it clear whether any potential procedure could cause him to miss time at the start of next season.
