It is not good news for Lakers for sure. Anthony Davis is one of the important players for Lakers and they could have some difficulties in playoff games if he doesn't get well until then.
If the injury will take a rest of the season for recovery, then good as the resting period is long. The Lakers can make playoffs even without Anthony Davis and that's for sure. Anyways, AD will undergo MRI on Monday so that's the only time we can speculate at least the most scenarios that the Lakers will face.
But even without AD, the Lakers still have the best bunch of good players in the league even on their bench.
Kahwi Leonard, Paul George, Kevin Durant, etc. these injuries struck some of the superstars. Hope they will be all healthy in the playoffs.
