Portland State offensive lineman Kyle Smith, a starting tackle from Elmira, died at his downtown apartment Wednesday evening.

Portland police said they are investigating Smith's death as a possible drug overdose.

Smith was a three-year starter and a second-team all-Big Sky Conference performer in 2015.

When police and medical personnel responded to a call at about 9:45 p.m. Wednesday in the 2000 block of Southwest Park Avenue, they found the 22-year-old Smith dead and discovered evidence of a possible overdose, police said in a news release Thursday afternoon.

Police said the investigation is ongoing and no arrests have been made. Toxicology results are expected to take several weeks, police said. Anyone who has information about Smith's death is asked to contact Officer Chris Verbout at 503-545-3481.

"I feel we have the most united, close-knit football team in America, and we just lost a major piece of that team in Kyle. Right now we have two concerns, Kyle's family and our football players," PSU coach Bruce Barnum said in a statement. "The program is being tested but we will come out of this on top."

Here is Smith's bio from the PSU athletic department website.

The Vikings canceled a scheduled Thursday practice and held a team meeting.

"We are deeply saddened by the loss of Kyle Smith," Director of Athletics Mark Rountree said in a statement. "Our thoughts and prayers are with his family at this time. I would ask the Viking family to support our student-athletes and coaches with love and caring during this difficult time. We must all must show resolve to cope with this tragedy as best we can."

Smith's death follows that of PSU linebacker AJ Schlatter, who died in January because of complications from tonsil surgery.
