Now, on Game Day morning, I see the cfl.ca/transactions list has been updated showing these moves by HAM:
HAM ADD FROM INJURED INT Will SMITH (LB) Texas Tech
HAM ADD FROM INJURED NAT Anthony WOODSON (RB) Calgary
HAM DEL NAT Everett ELLEFSEN (DE) McNeese State
HAM DEL INT Ross SCHEUERMAN (WR) Lafayette College
HAM EXT ON INJURED INT Jasper COLLINS (WR) Mount Union College – to Jul-14
HAM EXT ON INJURED INT Delano JOHNSON (DL) Bowie State – to Jul-14
HAM EXT ON INJURED NAT Mike JONES (WR) Southern – to Jul-14
HAM ADD INT Ross SCHEUERMAN (WR) Lafayette College
HAM REM UNS NAT Matt UREN (WR) Western University
So, officially, by this, both Ellefsen and Uren have been released, at least until further notice.
Here's an example of my comment, in the previous post, regarding the transactions list -- While Uren is now shown on the list as being "released from the non-active roster," he WASN'T on it. The club announced that he'd been added to the PR on July 3rd, but that never appeared on the transactions list.
