Other 2013 Supplemental Draft Trade Notes

 Toronto FC acquired the #38 pick in the 2013 MLS Supplemental Draft from Los Angeles Galaxy per the official selection order released by MLS on 17 January 2013. Trade details were not released. On 30 March 2011, Toronto FC acquired a then third-round selection in the 2013 Supplemental Draft from Colorado Rapids in exchange for midfielder Josh Janniere. The traded pick was reported as Colorado's natural selection. This pick should have become a fourth-round Supplemental Draft selection when the SuperDraft was shortened to two rounds but was not reflected in the official draft order released by MLS on 17 January 2013. It is assumed the trade was for a conditional pick and the conditions were not satisfied. References
