Willie Mitchell, Alexei Ponikarovsky out

Willie Mitchell and Alexei Ponikarovsky, both key offseason acquisitions by the Los Angeles Kings, will each miss significant playing time after suffering injuries Saturday night against Nashville, the team confirmed Monday.

Mitchell, a defenseman who signed a two-year, $7-million deal in July after spending the past three seasons with Vancouver, suffered a broken wrist in the second period against the Predators. He will be out approximately 4-6 weeks.

Ponikarovsky, a third-line forward who signed a one-year, $3.2-million deal in July after splitting time between Pittsburgh and Toronto last year, suffered a broken finger and will be out approximately four weeks.

The club would not disclose details of the injuries, but confirmed neither player would require surgery.

Mitchell, who was paired with Drew Doughty, has the only goal by a Kings defenseman this season.

Ponikarovsky had two goals and two assists in 13 games.

The Kings, off to their best start in 30 years, did not practice Monday.
