Brian Windhorst tweeted tonight that Cavaliers center Shaquille O’ Neal will have surgery on his injured right thumb tomorrow with a hand specialist in Baltimore. Windhorst inferred that the recovery time will most likely be 6-8 weeks for O’Neal which would effectively end his regular season. Shaq would most likely be back in time for a playoff series against the Orlando Magic and Dwight Howard – a primary reason for his addition to this Cavaliers squad. Windhorst tweeted that Shaq had been in excellent shape and that conditioning would most likely be the primary concern upon his return in the middle of the postseason. A postseason return is not guaranteed as the Cavaliers have not set an official timetable for his return. While there have been numerous reports since Friday that Zydrunas Ilgauskas intends to return to the Cavaliers, we still await official word from Z and his agent announcing this to be the case. In the interim, the Cavs will be without a true center for the foreseeable future.
