A couple of NFC North notes to take you through the evening:
Detroit released tight end Michael Gaines on Wednesday, four days after drafting tight end Brandon Pettigrew. It's possible you could see a further thinning of the Lions' tight end group; Will Heller and Casey Fitzsimmons are among the tight ends that remain on the roster.
Minnesota has invited the brother of Arizona receiver Larry Fitzgerald to its rookie camp this weekend on a tryout basis, according to Sean Jensen of the St. Paul Pioneer Press. Like his brother, Marcus Fitzgerald was a ball boy for the Vikings earlier this decade. The younger Fitzgerald went to Marshall as a running back but was switched to receiver.
