Mata suffered the injury when he collided with Jordan Farmar in the second half of Thursday's game with Washington State.
Mata underwent an MRI today. It showed the fracture to be high on the tibia, near the knee. No surgery is required but at least six weeks of recovery is expected, and possibly more.
Comments from Head Coach Ben Howland Friday:
"He's been playing his best basketball of his career over the course of the last few games. He's getting better, he's improving, This is a tough break for our team and Lorenzo."
On Michael Fey:
"He still has pretty significant swelling in there. I know they were going to try to get him on the treadmill (Friday) and see how it feels running. He hurt that, now, like 17 days ago. It's tough because it seems like it's taking longer than it should. But that's just unfortunate for Mike - and for us."
"It looks like he will be able to play some limited minutes."
On injuries, and whether he's ever seen anything like this season:
"No not even close. I don't know who else has, either. I've never heard of anybody who has had this many injuries. If you go back and chronicle all of the injuries that we have sustained from before we started practice to now, it's an unbelievable number of injuries for any team to sustain ever. It's just our task and our responsibility and I think the players have done a great job continuing to deal with adversity and guys being out because of injuries and still stepping up. That's what we have to continue to do."
On backing up to Ryan Wright at center:
"If Ryan Hollins can't play at all, probably Alfred Aboya is going to have to play minutes at the five now as well. What this opens up especially is more minutes for Alfred and more minutes for Ryan Wright."
