Anthony Davis says he will be fine after shaking off a bloodied nose to record 30 points with a season-high 22 rebounds to lead the Los Angeles Lakers past the Memphis Grizzlies 112-103 on Tuesday.

In the absence of the injured LeBron James, Davis was crucial for the Lakers who moved up to ninth – among the Play-In Tournament spots - in the Western Conference with the win, improving their record to 32-34.

Davis was floored and left clutching his bloodied nose with 6:43 remaining in the second quarter after copping an errant hand from David Roddy when securing a rebound.

The All-Star power forward was patched up and returned with a dominant performance, shooting 11-of-17 from the field with seven-of-nine from the free-throw line, with 22 rebounds including four offensive boards.

"It's still bleeding but we've got to win basketball games," Davis told ESPN during his on-court post-game interview.

"I do all I can to come out and compete every night and help this team get victories. The nose will be alright. We've got two days to recuperate and make sure it's still in place. I'll be alright."

Davis hailed the Lakers' defense for the win, coming two days after knocking off another Western Conference rival, the Golden State Warriors, 113-105 on Sunday.

The race for playoffs spots in the Western Conference is tight, with the Lakers only a few games behind the fifth-placed Dallas Mavericks and Warriors (both 34-32).

"It's a must-win," Davis said. "Every game we play from now is a must-win for us. Nothing changed tonight.

"Our ball club did a great job competing on both ends of the floor, little carryover from the game before against Golden State.

"We feel we owe this team one, we let one slip away in Memphis. Ja [Morant] was a big part of that. We wanted to come out and compete. All our guys stepped up tonight."
