Also, an MRI exam on forward Gerald Wallace's left ankle Saturday revealed no fractures or ligament ruptures. But Wallace likely will miss Sunday's game at Orlando after being injured on Friday.
General manager Rod Higgins announced this month they wouldn't sign Hughes because of his broken finger. But the injury has healed sooner than expected, and Hughes could be ready to play in about a week. He walked through plays and participated in shooting drills in practice Saturday.
Charlotte has been looking for help in the backcourt after trading Flip Murray to Chicago last month in a deal that brought forward Tyrus Thomas to the Bobcats. Coach Larry Brown coached Hughes in Philadelphia after the 76ers took him with the eighth pick in the 1998 draft.
The 31-year-old Hughes, who has averaged just over 14 points in his career, was traded by New York to Sacramento last month, then waived by the Kings. He's also played for Golden State, Washington, Cleveland and Chicago.
The Bobcats are hopeful Wallace could return within the week after he rolled his ankle on a hard foul in the closing seconds of the first half in Friday's 106-98 win against the Clippers. Wallace is averaging 18.5 points.
