After his college career with the University of South Carolina Gamecocks, Eidson spent a season with the
North Charleston Lowgators of the
NBDL. After a short stint with the
Boston Celtics, he signed a one-year deal with the
Gießen 46ers in the German
Basketball Bundesliga. The team, that was on the verge of relegation the season before, was brought back to life by Eidson, who led the 46ers to the Bundesliga playoffs against RheinEnergie Köln. In the decisive game five, Eidson scored 40 points, leading Gießen to a 3–2 series win and straight to the semifinals, where they lost against the eventual champion
GHP Bamberg. For his stellar performance, the Small Forward was named the 2004–05
Bundesliga Best Offensive Player. In a pre-season game versus
EnBW Ludwigsburg the following fall, Eidson suffered a torn ACL and sat out 172 days before returning to the starting lineup of the 46ers in a Bundesliga game against BG Karlsruhe. Only three games later, Eidson torched TBB Trier for 41 points. After the season, Eidson left Germany and signed with
Strasbourg IG in the
French Pro A, where he also gained
EuroCup experience. One year later, he signed with the Lithuanian powerhouse
Lietuvos rytas of Vilnius. When Eidson came to Lietuvos rytas, he quickly became a starter, and one of the team's leaders. His most memorable performance was in the
EuroLeague game against
Maccabi Tel Aviv, when he scored 28 points and led the team to victory.
FC Barcelona Bàsquet attempted to buy his contract out, but he remained with Lietuvos Rytas. In the 2008–09 season, he won the
EuroCup with the team also earning the
EuroCup MVP award, averaging 15.9 points and 21.3
PIR per game. He also led the team to a
Baltic League title that season, scoring a career high 41 points in the final against
BC Žalgiris, earning him the Baltic League Finals MVP award. In 2009, he moved to the
Israeli League club
Maccabi Tel Aviv, signing a two-year contract, estimated 1.5M
$ net income for the whole period. In his second season with Maccabi, Eidson led the team to the
EuroLeague Final with a great performance in the semifinal against
Real Madrid: 19 points on 66 percent shooting, along with eight rebounds and six steals for a PIR of 33. In the finals Maccabi lost to
Panathinaikos. In 2011, he left Maccabi Tel Aviv and signed a lucrative contract with
FC Barcelona. In Barcelona, Eidson was released due to cutting of the budget. His next station was the
Russian League club
UNICS, where he signed a two-year contract. He failed to
qualify with the team to the
2012–13 Euroleague, ending up instead in the
2012–13 EuroCup season. He was named to the
All-Eurocup Second Team in 2013. ==Personal life==
