NBA-National Basketball Association roundup

March 11 (The Sports Xchange) - One day after Chris Bosh expressed that he hopes to play again this season, the Miami Heat reiterated that there is no timetable for his return. The 11-time All-Star has been sidelined for more than a month due to a second round of blood-clot issues, and the possibility of seeing Bosh on the court isn't something that coach Erik Spoelstra is fretting about. "We don't have any kind of timetable or anything like that," Spoelstra told reporters on Friday prior to a game against the Chicago Bulls. Bosh last played on Feb. 9 and had to pull out of the NBA All-Star Game due to the medical problem. It was first reported as a calf injury and it later became commonly referred to as an injury related to blood clots, though the Heat have repeatedly refused to clarify Bosh's situation. - - - The Memphis Grizzlies signed guard Briante Weber to a 10-day contract after he was called up from the Sioux Falls Skyforce of the NBA Development League. - - - The Charlotte Hornets signed guard Jorge Gutierrez for the remainder of the season. The 6-foot-3 Gutierrez signed consecutive 10-day contracts with Charlotte on Feb. 20 and March 1. He has appeared in three games with the Hornets, averaging 3.0 points and 1.0 assists in 4.5 minutes per game. (Editing by Andrew Both)
