Otis Reese IV, a linebacker, joins Buffalo's roster via this transaction. Linebackers signed in these depth-churn moves are almost never fantasy-relevant unless they're immediately projected into every-down usage, and nothing in this reporting indicates that. Treat him as a non-factor for standard-format drafts; he's only worth knowing if you're deep into IDP formats, where added roster spots and potential defensive-snap opportunity in Buffalo's front seven could be worth a very late speculative note-to-self, not a pick.

Bottom line: no start/sit implication, no add worth using a roster spot on in redraft leagues, and Acker is a clean cut if he's occupying a slot anywhere. Confidence here is moderate — the two sources agree on the core transaction, but with one at 50% confidence, treat any downstream role projections for Reese as unconfirmed until camp reports clarify his standing on the depth chart.
