What happened: Smith sustained the non-contact injury during Sunday's 88-78 win over the Toronto Tempo, exiting with 3:15 left in the third quarter. She had made all four of her field-goal attempts before leaving.
Why it matters: Las Vegas is 26-13 and third in the Western Conference, behind the Minnesota Lynx and Golden State Valkyries, as it defends its title. A'ja Wilson, averaging 26 points, nine rebounds and two blocks, now carries a larger frontcourt load.
By the numbers: Smith averaged 11.7 points and 6.4 rebounds while leading the league with 63.8% shooting from the field.
What to watch: Las Vegas hosts Toronto on Friday before the FIBA World Cup break. Cheyenne Parker-Tyus, Brianna Turner and Justine Pissott are the frontcourt options to watch.
