Los Angeles Lakers star Anthony Davis said he felt "completely fine" before aggravating an Achilles injury in the NBA champions' defeat to the Denver Nuggets as he awaits the results of an MRI scan.

Davis, who posted 15 points in 14 minutes, suffered an Achilles strain in the Lakers' 122-105 loss to the Nuggets on Sunday.

The seven-time All-Star was held out of the second half as the Lakers saw their seven-game winning streak snapped.

Davis, who returned from a two-game absence caused by Achilles tendonitis on Friday, will undergo a scan on Monday.

"Just driving, I think that last step kind of re-aggravated the injury I already had," he said. "Now, it feels like an Achilles sprain. 

"Got an MRI tomorrow and try to figure out the next steps to get on the floor."

Davis – who insisted he and the Lakers followed all the right steps for his initial return – added: "Today was the first day that it felt completely fine. I didn't feel it at all this morning, afternoon, pre-game. I felt like I was heading in the right direction. 

"The treatment and rehab side. Another setback but it's part of the game. More so frustrated that I couldn't go out there and play, but you don't want to mess around with this type of injury. Trying to figure out the best steps.

"I felt great coming back the first time against Memphis [Grizzlies]. I'll do the same thing, the same steps to get it back right. Be smarter with it, I was smart the first time, but even smarter this time. Up the treatment more to get it back where it used to be to help the team."

Superstar Lakers team-mate LeBron James, who led the Lakers with 22 points, 10 rebounds and nine assists, added: "Just want him to be healthy and get back to full strength. All I care is about his health.

"It's definitely deflating anytime you lose a big player – a big guy on your team.

"We have a lot of things that's built in around AD and a lot of other players. When he goes down, you have to switch up. That hurt us."
