05/01 19:00 ET: A reminder on Liguilla tiebreakers. If the two teams are tied on aggregate goals at the end of the two legs, away goals will be used as the first tiebreaker to decide the winner. If both teams are tied on aggregate and away goals, Pumas will advance because they are the higher seed (higher seed rule). There is no added extra time, nor penalty kick shootout, in the quarterfinals or semifinals of the Liguilla.
05/01 19:00 ET: Pumas defender Luis Fuentes told Record yesterday that "Pachuca is a tough opponent, something is in the playoffs and they have great motivation because here you play a whole season and we must carry out our game with punch and intensity to get a head start in Pachuca." He also added that the team must carry on without Veron or Bravo tonight.
05/01 19:00 ET: Pumas would like to repeat the events of the Clausura 2009 final at the Estadio Hidalgo. However, there are no penalty kick shootouts in the quarterfinal and semifinal rounds of the Liguilla.
05/01 19:00 ET: Pachuca will get back defender Efrain Cortes from injury. The Colombian missed the Tuzos' 4-3 win against Queretaro due to injury.
05/01 19:00 ET: Pumas received some good news on the injury front. Attacking midfielder Daniel Luduena and striker Dante Lopez will be back in the side. Leading goalscorer Martin Bravo and captain Dario Veron are still out with injuries. Bravo has not played in his side's last six matches.
05/01 19:00 ET: This first leg of the tie will be shown on Azteca America, ESPN Deportes and can be watched on mobile devices on the WatchESPN app. (Reminder.)
05/01 19:00 ET: This tie is one of three quarterfinal matchups that are rematches of recent Liga MX championships. This match in particular is a rematch of the 2009 Clausura final in which Pumas defeated Pachuca 3-2 over the two legs.
05/01 19:00 ET: There is some interesting recent history between the two clubs regarding one of Pumas's players. Pumas attacking midfielder Daniel Ramirez had revealed to VAVEL Mexico that he and his family were extorted at Pachuca while in the Tuzos' youth academy. Ramirez has gone on to clarify the situation between he and Angel 'Coca' Gonzalez, the Pachuca coordinator of tryouts.
05/01 19:00 ET: Pumas end their 2014 Liga MX Clausura regular season campaign with the tournament's second leading scorer in Argentine striker Martin Bravo with nine goals to his name. The Argentine led the Golden Boot competition for much of the year before Enner Valencia started to score goals in bunches.
05/01 19:00 ET: Pachuca had been on a five-game winless streak before they emphatically came back from three goals down with fifteen minutes to play away from home to defeat Queretaro 4-3. Liga MX leading scorer Enner Valencia did not have a goal in that match, but two other players got braces in doing so.
05/01 19:00 ET: Pumas come into the match losing 1-2 away to Cruz Azul. But third-seeded Pumas had clinched their spot in the Liguilla place the week before, with a 1-0 win over Chivas de Guadalajara at the Estadio Olimpico Universitario. So, they rested a few players in their Mexico City derby clash.
