Peter Vermes is no stranger to the MLS Cup Playoffs.
The Sporting Kansas City boss is set to make his 13th career appearance in Major League Soccer's postseason — as a player or a head coach — when his side faces Seattle Sounders FC in Thursday's Western Conference Knockout Round at CenturyLink Field (9 p.m. CT, FS1 & UniMas).
In doing so, Vermes will enter rarefied air as one of only four individuals to either play in or coach a postseason game in 13 separate editions of the MLS Cup Playoffs — tied for the most in league history.
