There were several key names missing from the Seattle Sounders Concacaf Champions League roster that was released on Saturday (click for all the rosters). But before reading too much into the absence of recent signing Yeimar Gomez Andrade, it’s important to note that names can be added to the roster up until 44 hours before any game’s scheduled kickoff. The Sounders’ first game is on Thursday against CD Olimpia in San Pedro Sula, Honduras.

The most likely explanation for the Sounders’ having only 21 players filling their 35-man roster limit is that it was submitted before Gómez Andrade’s paperwork was finalized. Only players eligible to play in league games for the Sounders will be eligible for CCL.

The Sounders can continue to add players to their roster throughout the tournament as long as they have space. In addition to Gómez Andrade, the Sounders will almost certainly add other players currently in training camp. They’ll eventually have to cut the group of players they can select for their gameday roster to 23 players 44 hours before kickoff. They’ll then need to select 18 players from that group for their gameday roster.
