Bout agreements are pending to make the bout official for the September 19 pay-per-view event at the American Airlines Center in Dallas, Texas.
Swick (14-2), who had campaigned to fight Matt Hughes at the September event in his home state, has lost just once in 10 UFC bouts, losing to middleweight contender Yushin Okami in 2007 before dropping to welterweight in early-2008 and winning four-straight to make a case for a title shot.
Kampmann (15-2) has won 6 of his 7 UFC fights, including 2-straight at welterweight over Carlos Condit and Alexandre Barros following a loss to Nate Marquardt last September in his final middleweight bout.
UFC 103 is expected to be co-headlined by Cain Velasquez vs. Shane Carwin, and is also slated to include Frank Trigg vs. Josh Koscheck and Tyson Griffin vs. Hermes Franca.
