Greg Oden recently had a two-day visit with the Miami Heat.

Pat Riley confirmed the visit and restated his interest in signing Oden.

“We will explore that and see where it goes because of the possibilities,’’ Riley said of Oden, who has been plagued by knee problems since being the NBA’s No. 1 draft pick in 2007. “You go back to look at (Zydrunas) Ilgauskas. He had nothing but foot problems for about four years and everybody thought it was over. And the same thing happened with Kurt Thomas at the beginning of his career. There’s been a lot of players young in their careers that have had chronic injuries (and then) it doesn’t happen to them anymore. I think he’s such a young player and to be such a force, that you’d want to monitor him very closely.’’

The Heat would likely need to use their their $3.183 million exception to sign Oden.
