Ospreys Head Physio Chris Towers and his medical team will assess Adam Jones' condition this week ahead of the New Year's Day game against Cardiff Blues after he left the field with a neck injury in the defeat to the Scarlets on Boxing Day.
The Wales tighthead remains hopeful of featuring in the second of three festive derby clashes, which kicks off at 6.30pm at the Liberty Stadium, and Towers says he will be closely monitored throughout the week:
"Adam suffered a minor muscle spasm and we remain hopeful about his prospects of being available for selection on New Year's Day, subject to him undergoing a fitness test later in the week."
