Update (Thursday): The Cleveland Cavaliers issued a statement on Thursday, indicating that guard Kyrie Irving remains day-to-day after undergoing further examination as he awaits clearance under the NBA's new concussion policy. The Cavaliers next play on Friday night against the Milwaukee Bucks.
Original Post (Wednesday): The Cavaliers unexpectedly announced Wednesday night prior to the Cavaliers' game against the Clippers that Kyrie Irving sustained a concussion after a knee to the head Tuesday night versus the Heat.
Irving was evaluated overnight and after being diagnosed with a concussion, is out Wednesday and considered day-to-day. There's no official timeline for his return, which is no surprise since concussion recovery times can wildly vary depending on severity and the ambiguous nature of the recovery process.
Irving has posted a 21.6 PER this season, shooting 50 percent from the field, 40 percent from the perimeter, and 83 percent from the stripe, numbers which put him close to some of the best rookies in NBA history, while averaging 18 points and 5 assists for the surprising Cavs.
The NBA has discussed in recent months a new policy procedure for handling concussions.
