On the optimistic side, that timeline should have Rondo back for most or all of the conference finals and NBA Finals. Rondo has a history of hand injuries.
Rondo has a lengthy history of hand & wrist injuries including fractures of his left 5th metacarpal & his right thumb & 3rd metacarpal. He suffered a non-displaced volar plate avulsion fracture of his right ring finger earlier this year. https://t.co/9eSlidhUhx

The Lakers cannot sign a substitute player to replace Rondo (that is only for players with COVID-19 related absences, or who opted out, but not injuries).
Rondo came off the bench for the Lakers this season, averaging 7.1 points and five assists a game. More importantly, he was the guy running the offense when LeBron James was off the court, something that will be difficult to replace. He is not the defender and player he once was, but he fit with the Lakers.
The Rondo injury is not going to put the Lakers in danger in the first two rounds of the playoffs, but if he is not back and 100% in the conference finals (very possibly against a deep Clippers team) and the Finals, this will be a blow to L.A.
