Kiner-Falefa will undergo a CT scan Thursday on his injured left forearm to check for fractures, Tim Healey of The Boston Globe reports.
Kiner-Falefa was placed on the 10-day injured list this past weekend, but the Red Sox wanted to wait for the swelling in the infielder's arm to go down before sending him for testing. Once those results are in, the team will have a better idea as to how much time Kiner-Falefa might miss.
