Puk (shoulder) was shifted to the 45-day injured list Monday, Matt Kawahara of the San Francisco Chronicle reports.
The move is purely a procedural one, as Puk has already been ruled out for the year for shoulder surgery, a procedure he's expected to undergo sometime this week. It remains to be seen whether or not recovery from the surgery will cost him a portion of the 2021 season as well. The transaction clears space for Oakland to add Jake Lamb to the roster.
