Even though FC Dallas remains one of the best teams in MLS and are also one of the top candidates to win the MLS Playoffs, their chances of lifting the trophy at the end of the season have taken a massive blow following the injury of one of their best players.

According to reports, attacking midfielder and MVP candidate Mauro Diaz will miss the rest of the season with an Achilles injury. The former River Plate star suffered the injury during stoppage time against the Seattle Sounders this past weekend and he won't play again in 2016, so Oscar Pareja's team will have to face the postseason with their star playmaker sidelined.

​​Diaz underwent the surgery successfully on Wednesday and he should recover in time for 2017. But Dallas' chances of winning The Treble (U.S. Open Cup, Supporters' Shield and MLS Cup) are not the same one as last week. 

Even though they already won the Cup, they'll have a tough time in the playoffs without the 25-year-old playmaker. Diaz was the star of the team and his absence means that two of the team's best players (alongside Colombian winger Fabian Castillo who went out on loan to Turkish side Trabzonspor) are not with the team anymore.

Even though Dallas is already used to play without Diaz (since the playmaker has already missed 37 regular season games since his arrival in 2013) and considering the results have been better than expected, the Argentinian has traits that no other player on the squad possesses.

Players like Carlos Lizarazo and Mauro Rosales can replace Diaz and even play as an attacking midfielder in his spot, but they don't offer the pace, flair and creativity Diaz does.

After all, there's a reason why Diaz netted five goals and dished out 13 assists this season. Will Dallas overcome their star's absence, or will they fall short of the title once again despite their excellent regular season?
