Walker withdrew from Texas in October after he was suspended indefinitely following an arrest and subsequent misdemeanor charge of injury/dating violence for striking his girlfriend in a campus dormitory in September. Walker was arrested again a week after the incident for trespassing after he was banned from university property.
Walker, a Detroit native, told the Free-Press that he will begin classes at OU on Tuesday and is paying his own way. Oakland coach Greg Kampe said that the program will re-evaluate the possibility of a scholarship no earlier than April.
Walker will practice with the Golden Grizzlies, but will not be eligible to play in games the remainder of the season. His next court date has not yet been set.
"I've been informed that Martez is here on his own accord, paying his own way," Oakland associate athletic director Scott MacDonald said. "He's on our roster, not on our competitive roster at this point."
Walker averaged 4.7 points and 2.3 rebounds in 12.7 minutes per game as a freshman for Texas last season.
