Stephen Curry will return to game action on Saturday night against the Detroit Pistons.
Curry has been out of the Golden State Warriors' lineup since suffering a groin injury on Nov. 8.
"Steph is not going to play [Thursday]," Kerr said after Wednesday's practice. "He wants to play. He's ready to play, and we're just going to be extra cautious. Rick (Celebrini) felt very strongly, based on his years of experience doing this stuff, that it made sense to be extra careful, and he's going to wait. He will play in Detroit."
Curry spent several minutes after Wednesday's practice discussing his situation with Kerr and Celebrini.
Curry was hoping to play in Thursday's potential Finals preview against the Toronto Raptors.
"He's dying to play," Kerr said. "He loves playing in Toronto. He's got great memories of being here when [his father] Dell was playing with the Raptors. He's dying to play, but we rely heavily on Rick. Rick is really good at his job. He knows what he's talking about. And he thinks it makes a lot of sense to wait to give him two more days to be extra cautious, and that's what we're going to do."
"We obviously have a lot of smart people that are taking care of us and trying to make sure we're protected from ourselves in certain situations," he said. "Obviously, it's been three weeks or so, so I'm itching to get back. I'm obviously excited that the end is near. I love coming to Toronto, so it's a little disappointing."
