Passage: On September 9, 2008, Hager made his debut on the ECW brand under the ring name Jack Swagger, winning a match against a local competitor. He immediately established himself as a heel by starting a feud with Tommy Dreamer. He attacked Dreamer on the September 23 episode of ECW when Dreamer attempted to stop Swagger from attacking Chase Stevens. He later defeated Dreamer in a normal match and an "Amateur Wrestling Challenge" competition. After weeks of feuding, their rivalry ended in November in an Extreme Rules match, which Swagger won.He then sought to challenge Matt Hardy for the ECW Championship and was named the #1 contender on the December 30 episode of ECW. On the January 13, 2009 episode of ECW, Swagger defeated Hardy to win his first title in WWE, the ECW Championship. His undefeated streak in singles competition ended on the February 3 episode of ECW when he lost to Finlay in a non-title match. After successfully defending his title against Hardy at the Royal Rumble and Finlay at No Way Out, Swagger began a feud with the returning Christian, who he lost the ECW Championship at Backlash, ending his reign at 104 days. He attempted to regain the title against Christian at Judgment Day and in a triple threat hardcore match at Extreme Rules also involving Dreamer but was unsuccessful in both attempts. His attempt to win the ECW Championship at The Bash in an ECW Championship Scramble also failed.

Question: When did Swagger's undefeated streak end?
February 3
