Adrian Wojnarowski of Yahoo! Sports reports on Twitter that the Portland Trail Blazers have agreed to sign University of Oregon forward E.J. Singler to a training camp contract.

Joe Freeman of The Oregonian confirmed the report.

Update (Monday) : The Blazers confirmed the signing in a release on Wednesday.

Singler, who spent four years at Oregon, joined the Blazers for pre-draft workouts on June 7 and June 19. He was not ranked in the DraftExpress.com top 100 and he eventually went undrafted in the 2013 NBA Draft.
