GRAND RAPIDS, MI – The missing puck from Gustav Nyquist’s first NHL goal has been recovered, but the Detroit prospect is uncertain when he will get it back.

Kent County sheriff’s detectives confirmed they have recovered the framed and signed puck, which disappeared in August, along with a number of other items owned by Nyquist and two teammates from a Grand Rapids-area storage unit.

Police said the puck is secure, but it cannot immediately be returned because it is potential evidence.

“We do have the hockey puck – we’ve recovered that,” said sheriff’s Lt. Ron Gates. “We’ve been in communication with Gustav.”

Police released few details because the recovery is part of a “complex,” months-long investigation, detective Bill Marks said.

He said the puck is “being held. It’s not going anywhere.”

Nyquist, who’s currently with the Grand Rapids Griffins, said he received a call from the department alerting him of the recovery.

“Obviously, I’m stoked that the puck is back, and that’s a big thing for me,” he said. “It’s going to be on my wall one day when I get a house, and I’ll be proud of it, for sure.”

Nyquist, who expressed his gratitude to the department for the recovery, was not given a time table when he might be reunited with the puck, nor whether other missing items – such as the framed scoresheet from his first NHL game and other personal items – were recovered.

“They couldn’t really tell me much, but they said don’t get your hopes up” in receiving other items, he said. “But I’m just happy to know they have the puck.”

Nyquist, 23, returned to the Griffins on Monday following his third stint this season with the Red Wings. Considered one of Detroit’s top prospects, he leads the AHL in scoring with 60 points (23-37-60) in 57 games.

The Griffins play at Peoria tonight. They are home Friday against Lake Erie.

Nyquist made his NHL debut with the Red Wings on Nov. 1, 2011, against Minnesota. His first goal came March 26, 2012, against Columbus.
