Update, 11:27 p.m. CT: FOX Sports is reporting that Chryst is indeed the frontrunner for the Wisconsin job, and that he's on his way to Madison.

There is also the photo below, reportedly of Chryst at the Pittsburgh airport on Thursday. The tweet was sent at 9:51 p.m., though it's unclear whether Chryst was departing or arriving at the airport.

Update, 10:30 p.m. CT: Jeff Potrykus of the Milwaukee Journal Sentinel has some confirmation of mutual interest between Wisconsin and Chryst, plus a few more enticing details about Chryst's possible staff.

Just talked to source on Paul Chryst, poised to be #Badgers coach: I felt this was the scenario from Day 1. (more) — Jeff Potrykus (@jaypo1961) December 12, 2014

More on #Badgers and Chryst: He will put together a good staff. Source believes Chryst can bring Joe Rudolph back. — Jeff Potrykus (@jaypo1961) December 12, 2014

Source on former #Badgers assistant Rudolph: He can sell Wisconsin. Source also believes Chryst can get Bostad back. — Jeff Potrykus (@jaypo1961) December 12, 2014

Joe Rudolph is currently the offensive coordinator and assistant head coach (tight ends) under Chryst at Pitt. He was the tight ends coach and recruiting coordinator under Bielema at Wisconsin from 2008-11. It would be interesting to see what his return would mean for Chris Beatty, Wisconsin's current wide receivers coach and recruiting coordinator.

Bob Bostad was Wisconsin's offensive line coach under Bielema from 2008-11 and was also UW's tight ends coach in 2006-07. He also held "run game coordinator" duties in both positions. Bostad jumped to the NFL in 2012, coaching the Tampa Bay Buccaneers' offensive line from 2012-13.

Ben Worgull of BadgerNation.com reports that a new head coach could be named in the next two days, possibly as soon as Friday, though he doesn't indicate if Chryst is the favorite.

If this does come to fruition, it would be some pretty quick work by Alvarez. It would also make for a solid reunion of Wisconsin's top assistant coaches under Bielema. Who would've seen that happening two years ago?

Wisconsin athletic director Barry Alvarez has a meeting "imminent" with Pittsburgh head coach Paul Chryst, Madison.com reported Thursday night.

The report suggests Alvarez has "isolated his first priority" as Chryst in his coaching search, which began Wednesday when Gary Andersen abruptly resigned in order to become the Oregon State head coach. Chryst, a Madison native, was Wisconsin's offensive coordinator from 2005-11. He was also UW's tight ends coach in 2002.

According to Sam Werner of the Pittsburgh Post-Gazette, Pitt issued the following statement on Thursday:

Official comment from #Pitt regarding any Paul Chryst/Wisconsin speculation: pic.twitter.com/XKL0p1fO0D — Sam Werner (@SWernerPG) December 12, 2014

Chryst was hired by Pitt in 2012, going 6-7 that season and 7-6 in 2013. This season, the Panthers went 6-6 and will face Houston in the Lockheed Martin Armed Forces Bowl on Jan. 2.

Chryst oversaw some of the great "Wisconsin just scored again" offensive performances while working under Bret Bielema at Wisconsin.

Wisconsin's offense under Paul Chryst, 2005-11 Points / game (rank) Pass yards / game (rank) Rush yards / game (rank) Yards / play (rank) 2011 44.1 (8th) 234.3 (61st) 235.6 (11th) 7.0 (5th) 2010 41.5 (5th) 199.5 (75th) 245.7 (12th) 6.7 (13th) 2009 31.3 (25th) 213.1 (66th) 203.8 (15th) 5.9 (33rd) 2008 27.5 (47th) 188.1 (84th) 211.2 (14th) 5.8 (34th) 2007 29.5 (50th) 208.0 (72nd) 200.8 (22nd) 5.7 (41st) 2006 29.2 (26th) 211.5 (50th) 161.7 (37th) 5.6 (44th) 2005 34.3 (14th) 228.4 (51st) 168.2 (37th) 5.7 (35th)

When news of Andersen's departure first broke, Chryst was widely one of the first names mentioned as a possible replacement. B5Q's Andrew Rosin listed Chryst in his first rundown of potential targets for Alvarez:

Hey! He's still possible, and while he's been eminently mediocre at Pitt (19-19), he's still someone who knows how to build an offense. Joel Stave would absolutely have a shot at a spectacular senior season if the Badgers go bring the Madison native home. Truth be told, this is a name that's lost some luster after multiple seasons in the ACC where the Panthers have been on the treadmill to nowhere, but you will see his name called.

Of course, this is merely the first rumored target for Wisconsin's coaching search. With the position being at a state institution, Wisconsin's coaching search must follow certain protocol. The job posting is publicly listed, for instance.

Its state law that any state job opening must be open for 2 weeks before the position can be filled. Last time GA was hired on day 14. @B5Q — Luke Mueller (@Luke_Mueller24) December 12, 2014

Alvarez is currently in Lake Buena Vista, Fla., for ESPN's Thursday night College Football Awards show, where Wisconsin running back Melvin Gordon was announced as the 2014 Doak Walker Award winner.

Alvarez has said he plans to work quickly in hiring a replacement, ideally before Wisconsin faces Auburn in the Outback Bowl on New Year's Day. He expressed as much in his first public comments following Andersen's departure on Wednesday.
