Bichette will be sidelined 4-to-6 weeks but won't require surgery on his fractured left hand, Gregor Chisholm of MLB.com reports.
Bichette sustained the broken hand during Triple-A Buffalo's game on Monday as he was hit by a fastball up and in. The highly touted prospect still could make his major-league debut at some point this season, but is now likely sidelined through the end of May.
