From the tweets of tribjazz & lockeonsports,
Carlos Boozer has a moderate calf strain and will be reevaluated Monday. The Jazz said the crutches were precautionary.
From Locke,
The #utahjazz are calling the Carlos Boozer injury a moderate strain. Boozer will go through treatment again this afternoon
Locke goes on to say that Boozer thinks he'll be out about 10 days. That would put him out until the All-star break. I think we'll get his slack picked up by Millsap and AK but that's a stretch of games over some good teams that we'll be without him. We face Portland, Dallas, Denver, and LA. They're all at home, so that's a plus.
Let's hope this doesn't stretch out longer.
