O'Shaughnessy caught one pass for 16 yards in the Bears' 27-11 preseason win over the Seahawks' on Thursday.
O'Shaughnessy took the field on the second drive, right after the Bears took their first-team offense off the field. His reception came from backup quarterback Trevor Siemian. The tight end will likely continue to battle with Ryan Griffin for the No. 2 tight end role behind Cole Kmet.
