A product of Real Madrid's youth system, Madrid-born Contreras picked up a UEFA Champions League winner's medal in 1998, even though he did not play a minute during the season. He spent four years with the B-side, Real Madrid Castilla, and appeared in four first-team games in the 1998–99 campaign as the former finished runner-up; for 1996–97, he was loaned out to Rayo Vallecano where he only missed one league match in 42, being however relegated from La Liga.
Contreras signed for Real Betis in the 2003 summer, making 22 league appearances during his debut campaign but none in the following due to injury and the rise of Toni Doblas. In 2005–06 he competed in both the UEFA Cup and the Champions League, where he kept a clean sheet against Chelsea in a 1–0 group stage win.
Loaned to Cádiz CF (also in Andalusia, Segunda División) for 2007–08, alongside Dani, Contreras was released at the end of the season. He subsequently retired from the game, and rejoined former club Málaga as a goalkeeping coach.
Contreras was third-choice for the Spanish national team in the 2002 FIFA World Cup, a late addition to coach José Antonio Camacho's squad after first-choice Santiago Cañizares was injured in a freak accident. He received his only cap in a 0–0 home draw against Paraguay in Logroño, on 16 October of that year.
