Ducks' Leo Carlsson out up to six weeks with knee sprain

Anaheim Ducks rookie forward Leo Carlsson will be out for four to six weeks with a sprained right knee ligament.

The Ducks announced the extent of the injury for the No. 2 overall pick in last summer's draft before losing to theSeattle Kraken3-2on Saturday night in their final game prior to the holiday break.

Carlsson, who turns 19 on Tuesday, was hurt during Anaheim's home loss to the Calgary Flames on Thursday. Carlsson couldn't put any weight on his right leg after Flames defenseman MacKenzie Weegar fell on Carlsson's side.Although the injury looked potentially severe, the Swedish playmaker apparently won't need surgery on any torn ligaments in his knee.

"Weegar there was lunging, and then Leo lost his balance," Anaheim coach Greg Cronin said after the game. "You could see when Weegar fell on him, any sport when that happens, it's not good."

Carlsson is off to a solid start in his first NHL season with eight goals and seven assists in 23 games while playing as the Ducks' first-line center.

Anaheim defenseman Radko Gudas also was ruled out against the Kraken with a lower-body injury. He will be reevaluated after the holiday break.

Star forward Trevor Zegrasreturned against the Kraken, following a 20-game absence with a lower-body injury, and scored in the third period. He finished with 18:32 in ice time across 20 shifts.

The No. 9 overall pick in the 2019 draft, Zegras, 22, has two goals and an assist in 13 games after posting a career-high 65 points, including 23 goals, last season in 81 games.
