The Clippers have a 14-man roster, leaving them with room to sign another player to a 10-day contract if Rivers desires to.
Despite all the injuries, Rivers said his team isn't giving in to excuses.
"I get the sense sometimes [but] I don't right now. I think they're ready," Rivers said. "I think this team knows me by now. We're not making any excuses. That doesn't work in our league, and no one cares. They really don't. No one really cares about anything but wins.
"The only thing they want you to explain is that. That's what I tell my guys all the time: find a way to win the game. We'll worry about all the other stuff later. But tonight, we have to find a way to win this game."
The Clippers signed guard Nate Robinson to a second 10-day contract Tuesday.
Before Tuesday night's game against Charlotte, Robinson had played in five games with the Clippers. Robinson was averaging 4.0 points per game in 14.6 minutes per game. He was shooting just 24.1% from the field, 27.3% from three-point range.
"I still like his energy," Rivers said. "The shots you figure eventually will fall anyway. That's what he does. And he'll take some bad ones and make them and miss them. That's just Nate. But what we need him to be is an energy player."
Robinson will be counted on to not only back up Chris Paul at point guard, but to fill the void left by Crawford being out.
"You've just got to be yourself," Robinson said. "If they like you, they like you. If they don't, they'll let you know."
