The Jack Gurr "Waiver" thing seems an odd one. From the following it seems it means he is free for another MLS club.

Waivers
A club may place a player on Waivers at any time during the regular season at which point he is made available to all other MLS clubs. The Waiver Claiming Period shall commence on the first business day after the League delivers notice to clubs and expires at 5 p.m. ET on the second business day. If a player is not selected off Waivers ("clears Waivers") then that player is available to all MLS clubs on a first-come, first-served basis.

Waiver Order

If only one Club puts in a claim for a player placed on Waivers, such Club shall be awarded the Player.

If more than one Club puts in a claim for a player placed on Waivers and, if applicable, the highest offer has been provided by multiple Clubs (assuming all claiming Clubs have claimed the same number of Players from Waivers in that MLS Season), then the League shall award the Player to the Club with the lowest average points per Regular Season Game (i.e., points per game) at the time the Player is placed on Waivers.

If the Waiver takes place prior to all clubs playing in at least three MLS League Season games, priority is granted in the reverse order of the previous MLS season's performance, taking playoff performance into account first, with clubs eliminated from playoff contention at the same stage separated according to their point totals through the end of the regular season. New expansion clubs shall be at the bottom of the Waiver Order until all clubs have played at least three MLS League Season games.
