LeBron James is questionable for the Los Angeles Lakers' home game against the Portland Trail Blazers on Sunday after suffering a left calf contusion, the team have announced.

James sustained the injury during the first quarter of Friday's 122-119 in-season tournament road win over the Phoenix Suns, taking a blow from Kevin Durant's knee as he drove to the basket.

The NBA's all-time leading points scorer received treatment on the bench, but composed himself to finish with 32 points, 11 rebounds and six assists as Los Angeles ended a three-game losing run.

However, James was seen limping after the win, which brought the curtain down on the Lakers' four-game road stretch, and he subsequently told reporters his shin was sore.

 "It never loosened up," James said of his shin after Friday's game. 

"[It] pretty much locked up right then and there. So I tried to keep my composure, make sure I was okay and try to keep it stretched out and as loose as possible and play the game and be effective.

"[It's] pretty sore right now. Obviously because the adrenaline is calming down and I've iced it, now it's pretty sore."

James was listed as questionable on the Lakers' injury report ahead of Portland's visit to Crypto.com Arena, while Anthony Davis and Jaxson Hayes were deemed as probable.

Injuries have hampered Los Angeles during an underwhelming start to the season, with Friday's victory lifting them to 4-5 after a run of three successive road losses against the Orlando Magic, Miami Heat and Houston Rockets.
