From Sporting News: The Boston Celtics have agreed to terms with veteran point guard Carlos Arroyo on a contract for the remainder of the season, according to The Boston Globe and Boston Herald. Arroyo, 31, was waived by the Miami Heat earlier this week. He averaged 5.6 points and two assists for Miami. With Boston, Arroyo will serve as a replacement for Delonte West, who will miss time with a sprained ankle, and a backup to Rajon Rondo, who is averaging 37 minutes. "The guy I've got to keep down more is Rondo," Celtics coach Doc Rivers said after Rondo played nearly 42 minutes on Friday against the Golden State Warriors, according to Comcast Sportsnet New England. "Even though he's young, he's still playing too many minutes the last four or five games. With Delonte out, that's put a lot of stress on us as well." Rondo has missed time with ankle and hamstring injuries this season. Boston also may have looked at former Spurs and Wizards point guard Antonio Daniels, 35, who is attempting an NBA comeback and currently playing for the NBA Development League's Texas Legends, according to the Herald. Arroyo became expendable in Miami after the team signed Mike Bibby, who was bought out by the Wizards after they acquired him in a trade with Atlanta. To make room for Arroyo, Boston opted not to sign backup center Chris Johnson to another 10-day contract.
