Montepaschi Siena guard Bo McCalebb left in pain in the game against Scavolini Tuesday and is keeping the staff on their toes until medical exams give an estimation.

The 26-year old American had just returned to action in the game against Scavolini for the Italian league, yet he felt pain where he was operated last year (when he was forced to sit out the entire Top 16 of the Euroleague) and he didn’t return on the court for the second half.

Medical exams will give an estimation of the situation and surely everybody in Siena is hoping that there is no serious injury.
