The 49ers are expected to part ways with Jim Harbaugh in less than 72 hours, and interested parties are positioning themselves to land the successful, if controversial, head coach. According to Bruce Feldman of Fox Sports (Twitter link), the University of Michigan, which reportedly has a six-year, ~$50MM offer on the table, will send officials (and its search firm) to the Bay Area this weekend to meet with Harbaugh. Ian Rapoport of NFL.com confirms the Michigan news, and reports that the Raiders will also speak with Harbaugh this weekend (Twitter link). Rapoport also adds (via Twitter) that Harbaugh will resolve his situation with the 49ers before he meets with either entity. Here’s more from around the league…

• Tony Pauline of DraftInsider.net passes along the latest regarding NCAA draft entrants, reporting that while defensive tackle Rakeem Nunez-Roches of Southern Mississippi and running back Devontae Booker of Utah will likely enter the draft (Twitter links), Rutgers receiver Leonte Carr will likely return to school for another year (Twitter link).
• Meanwhile, UCF receiver Breshad Perriman didn’t receive a top-three round grade from the NFL Draft Advisory Board, so he’s still considering whether or not to enter the draft, tweets Pauline.
• With one week left in the NFL season, Jason Fitzgerald of Over the Cap updates both the playoff odds and the favorites for the No. 1 overall pick in the draft.
• While the Titans will have a chance to draft either first or second in the 2015 NFL Draft, Zach Mettenberger believes the team already has the quarterback of its future, writes Jim Wyatt of the Tennesseean. “There’s not another guy out there who can do what I can do and bring what I can bring to this game.,” said Mettenberger. “Obviously (the Titans) have seen how hard I work and know that I’m a gym rat, and know that I am going to continue to get better. Really all I can do is continue that and show that I am going to continue doing it.”
• Ex-Rams receiver Austin Pettis, released by St. Louis on October 20, worked out for the Chargers today, according to Adam Caplan of ESPN (Twitter link). San Diego’s Keenan Allen is nursing a collarbone injury, so Pettis could provide some insurance at the WR position.
• After releasing defensive tackle Travian Robertson earlier today, the Seahawks don’t plan on making a roster addition before Sunday’s contest, tweets Bob Condotta of the Seattle Times.
