Cousins, who is listed as questionable for Monday's game, left Saturday's win over the Oklahoma City Thunder in the fourth quarter with what was initially listed as a sore right ankle.
Golden State coach Steve Kerr didn't sound too concerned about Cousins' injury Saturday, but Bogut's appearance in San Antonio comes as a bit of a surprise in that Kerr said earlier this week that he didn't want Bogut to have to fly across the country after flying across the world from Sydney -- where he just finished his season in Australia's National Basketball League.
Bogut spent four seasons with the Warriors before re-signing with them for the stretch run last week. The Warriors have a back-to-back in San Antonio and Minnesota on Monday and Tuesday.
Warriors star forward Kevin Durant is expected to play Monday after missing the last week because of a right ankle injury.
