Anaheim Ducks goaltender Ryan Miller had surgery on his left wrist to remove a bone fragment, the team announced Monday.

Miller is expected to be sidelined for six weeks and not miss the start of training camp.

Miller, who will turn 38 in July, appeared in 28 games for the Ducks this season, including 21 starts. He posted a 12-6-6 record with a 2.35 goals-against average, .928 save percentage and four shutouts.

The Ducks also announced some changes to their coaching staff on Monday.

Marty Wilford has joined the team as an assistant coach. He had been an assistant coach with the team’s AHL affiliate in San Diego for the past three seasons.

The Ducks signed San Diego head coach Dallas Eakins to a multi-year contract extension. In three seasons with the Gulls, he has a 118-71-15 record.
