The Colorado Rapids are set to acquire former Seattle Sounders midfielder Marco Pappa, according to a Major League Soccer source.

Terms of the deal were not immediately known. Pappa earned $75,000 in 2015, according to figures released by the MLS Players Union.

The 28-year-old midfielder from Guatemala City was pulled from the re-entry draft player pool moments before the draft was to take place, fueling speculation of a deal.

The Rapids passed their pick (No. 2 overall) in the re-entry draft. FC Dallas traded up to the top slot and selected former Portland Timbers forward Maximiliano Urruti.

Pappa has 35 goals and 27 assists in 161 MLS games (142 starts) since 2008. The Guatamalan international spent the last two seasons in Seattle. He played for the Chicago Fire from 2008-2012. He appeared in 11 games (one start) for SC Heerenveen of the Dutch first division between 2012 and 2013, notching two assists.

In July, Pappa was arrested for DUI and speeding and had to undergo an assessment by MLS’ Substance Abuse and Behavioral Health Program.

According to an arrest report obtained by the Seattle Times, Pappa was going 84 mph on the interstate and had a blood-alcohol level twice the legal limit.

He scored a goal and had one assist in four games after his return from suspension.

Pappa has 10 goals and three assists in 37 caps with the Guatemala national team.

Listed at 5-foot-10, 155 pounds, Pappa is a strong passer who likes to play balls in the air, especially with his left foot.
