Tim Duncan made an appearance at the San Antonio Spurs' training camp workout on Wednesday.

Duncan's role within the franchise remains unclear now that he's retired.

"When I got done arguing with him about why he's been fined for not showing up the last few days, we got that out of the way first. Most people under contract are required to show up for their jobs," Gregg Popovich said jokingly. "He said he didn't have a contract. But I told him I thought we had a verbal contract, and I thought that was just as good as written. We're having a tough time right now, the two of us, trying to get him straight. He's always been tough to manage, especially so now that he's retired."

Duncan served as a spectator as the club scrimmaged Wednesday and could be seen conversing with former teammates as they took part in an after-practice shootaround.

Popovich mentioned Monday that Duncan would remain involved with the team and joked that he would be "the coach of whatever he feels like." Popovich said there is no room for Duncan on the bench during game situations and joked that he's "too smart for that" anyway.

Like Popovich, R.C. Buford said Duncan's role will be "whatever he decides it to be." But first, the Spurs would like Duncan to adjust to life after basketball, while finding the niche in which he's most comfortable.

"I think he's learning about life after playing," Buford said. "And he can impact us in so many ways. I think we need to sit back and get a better understanding of how he feels like he wants to fit in and what works for his family. Then we'll figure it out from there. But the gym feels better when he's in it."
