Stop If You’ve Heard This Before: If UCLA basketball is in the news, you can bet that an injury is the subject. And you’d collect on the latest word out of Westwood. Sophomore forward Lorenzo Mata is down with a knee injury that will sideline him for at least six weeks. Mata injured the knee during UCLA’s 63-61 win against Washington State Thursday. Mata joins the infirmary list that already features Jordan Farmar, Josh Shipp, Cedric Bozeman, Ryan Wright and Ryan Hollins. [1/15/06]
