According to Yahoo Sports, at least two NBA teams were contacted this summer about their potential interest in McGrady as he and Bryant worked out three days a week during August.
McGrady, 35, retired from the NBA last in August 2013 and pitched for the Sugar Land Skeeters of the independent Atlantic League this past spring.
McGrady is slated to go to China in October for a basketball tour.
“Yes, I was working out with K.B. to get in shape and see how my body feels," McGrady told Yahoo Sports in an email. "The comeback will not happen, unless I have the drive whenever I get back."
McGrady was a seven-time All-Star and two-time scoring champion over 15 NBA seasons.
