For the second time in three seasons North Carolina will begin the season while its senior point guard, and unquestioned on-court leader, recovers from a broken bone in his hand. The school announced on Monday that Joel Berry, who earned Final Four Most Outstanding Player honors while he helped lead to the Tar Heels to the national championship last April, had suffered a broken bone in his right hand. Berry is expected to miss approximately four weeks. The details of how Berry endured the injury weren’t immediately clear. The announcement of it, though, comes 18 days before UNC begins the season on Nov. 10 against Northern Iowa. It seems certain that Berry will miss that game, and another one on Nov. 15 against Bucknell. If he does only miss four weeks from Monday, though, he could conceivably return when UNC begins a trip west with a game at Stanford on Nov. 20. After playing there, the Tar Heels travel to Portland, Ore., for three games in the PK80, a 16-team Nike-sponsored tournament.
