The temperature was ice cold in Edmonton on Saturday night. There were snowflakes in the air. But Puerto Rico coach Adrian Whitbread’s temper was white-hot.

From the league: "The NASL has opened an investigation with respect to an allegation that racially abusive comments were made by one player to another player during the FC Edmonton vs. Puerto Rico FC game on August 28, 2016. Per League policy, no further comment will be made while the investigation is ongoing."

How negative was the road side? Even when PRFC was up a man, the players opted for a clock-killing strategy. Late in the game, up a player, the visitors chose to take the ball into the corner and kill time rather than try to create scoring chances.

FC Edmonton narrowed the gap to four points between itself and the Carolina Railhawks for the final NASL playoffs spot with a 1-0 home win Sunday over an undermanned and overmatched Puerto Rico Islanders side.

After two losses on the road, coach Harry Sinkgraven unveiled a new-look lineup. Instead of a 4-3-3, FCE switched to a 4-4-2, with Shaun Saiko moved from the outside to a free attacking midfield role behind the strikers.
