Kyrie Irving to face minutes restriction Friday due to knee injury

Kyrie Irving said in September he was ready to 'kick some butt' with no restrictions.
Underdog NBA reports that point guard faces a minutes restriction on Friday.
The limitation is related to a knee injury, according to coach May. Irving remains active for the game but will have his playing time capped.
The Mavericks play on Friday. A reduction in Irving's workload leaves additional minutes available for the remaining Dallas guards in the rotation.
