In the end, it was none of the above.
The Cubs traded Dempster to the Texas Rangers just minutes before Tuesday's 4 p.m. ET deadline, according to ESPN's Buster Olney.
It's still unclear at this point who the Cubs have acquired in the deal.
The 35-year-old Dempster is 5-5 this season with a 2.25 ERA in 16 starts. The veteran right-hander had put together a 33-inning scoreless streak earlier this season, but he's struggled as of late. He gave up a total of seven runs in just 12 innings in his last two starts in a Cubs uniform, both losses.
It will also be Dempster's first time pitching in the American League. He's 11-15 with a 4.63 ERA in 50 games and 35 starts against American League clubs during interleague play. He's also allowed 30 home runs in 299 1/3 innings pitched in those interleague matchups.
