Someday, the Green Bay Packers will play a regular-season game in London. For this year, they might have to settle for playing a preseason game in Winnipeg.

A preseason game against the Oakland Raiders is inching closer to becoming reality, with an official announcement perhaps coming soon, team President Mark Murphy said in Milwaukee on Tuesday.

The Raiders would be giving up a home preseason game in something of a lame-duck final season in Oakland before moving to Las Vegas for the 2020 season. The Raiders have a lease agreement in place with the Oakland Alameda Coliseum Authority for the 2019 season. There are scheduling conflicts, though. The Oakland A’s baseball team will be at home the weekend of Aug. 24-25. The Packers-Raiders game is scheduled for somewhere in the window of Aug. 22 through Aug. 25.

The Canadian cities of Winnipeg and Saskatchewan were in the running for the game. The Saskatchewan RoughRiders, however, are scheduled to play a home game on Aug. 24. The Winnipeg Blue Bombers, on the other hand, will play at Edmonton on Aug. 23.

In a statement to the Winnipeg Free Press, the team on March 26 said: “The Winnipeg Football Club is always exploring opportunities to host events at Investors Group Field. At this time, the Club has no further comment.” A couple weeks later, NFL officials arrived in Winnipeg to tour Investors Group Field and its facilities.

Green Bay is one of two teams that have not played in the NFL’s International Series. With Carolina scheduled to play in London this season, that will leave only the Packers to have not played a regular-season game in England or Mexico. The Packers did play a preseason game in Toronto in 1997 and Tokyo in 1998.

“The league cannot make us give up a home game. We've made that clear. We're not going to do that,” Murphy said on ESPN Wisconsin’s “Wilde and Tausch” radio show last week. “The only way we're going to play in London is the league convincing a team that has a home game against us (to give up a home game).”

The Packers will kick off three weeks of voluntary organized team activities next week, with practices on May 20, 21 and 23, May 28, 29 and 31, and June 3 through June 6. Teams are allowed to practice 10 times during OTAs. After that, the Packers will hold their mandatory minicamp from June 11 through June 13.

The annual shareholders meeting will be held on Wednesday, July 24, at 11 a.m. at Lambeau Field. Training camp begins the next day; coach Matt LaFleur said following the draft that he has not finalized his inaugural training camp schedule.

The preseason will start with a home game against the Houston Texans on Aug. 8. In the days before that game, the teams will hold joint practices in Green Bay.

“I’ve done it the last two years,” LaFleur said at the NFL annual meetings in April. “In Tennessee, we scrimmaged vs. Tampa before our second preseason game, which I thought was awesome. You can get so much good-on-good work. And quite honestly, you can practice your guys and not have to play them as long in the preseason game.”
