* UConn coach Jim Calhoun will undergo surgery next week to address a lower back condition and he will miss the Huskies' next two games. The university said the status of the Hall of Fame coach, who has been on a medical leave of absence since Feb. 3, will then be evaluated on "a day-to-day basis."
Calhoun is expected to be hospitalized for 1 or 2 nights and then continue his recovery at home following Monday's procedure. The surgery is intended to alleviate spinal stenosis, a painful narrowing of the spine, normally associated with aging and sometimes with arthritis.
* The defamation lawsuit filed by two former ball boys against Syracuse University and head basketball coach Jim Boeheim will be heard in Syracuse, a judge ruled. Bobby Davis and Michael Lang filed their suit in New York City, claiming Boeheim slandered them by saying they were out for money after their allegations of abuse by former assistant coach Bernie Fine surfaced in November. They fought a motion by the school and Boeheim to hear the case in Syracuse, where they don't believe they'll get a fair hearing because of Boeheim's high standing in the community. But Supreme Court Justice Brian DeJoseph said the two men did not provide sufficient proof that Syracuse jurors would be biased. He said while there may be local residents unqualified to serve on a jury for this case, there are about 350,000 people in the county to choose from.
* Delaware athletic director Bernard Muir and Michigan State athletic director Mark Hollis are joining the NCAA Division I men's basketball committee. The two will start Sept. 1.
