The University of Utah's J.J. O'Brien shoots as Grand Canyon's Rony T. Chatchoua defends. O'Brien will be out approximately 4-6 weeks with a stress fracture in his foot.

SALT LAKE CITY — Utah played without freshman forward J.J. O'Brien against Montana on Wednesday night after O'Brien suffered a stress fracture in his right foot earlier this week. He is expected to be out approximately 4-6 weeks, according to head coach Jim Boylen.

"It's a blow to our program," said Boylen. "I think he's the best freshman we've recruited since I've been here. He was a starter, a versatile, athletic wing and he showed some signs of what he can be in our first game. I'm disappointed for him. We've had to adjust and we'll keep adjusting."

The 6-7 O'Brien, who came to Utah from Rancho Cucamonga, Calif., started Utah's season opener, scoring six points and grabbing eight rebounds against Grand Canyon.
