In March 2014, Sinaga was banned for two matches by the PSSI for excessively cursing at a referee in a match against Semen Padang F.C. on February 16, 2014.

On June 10, 2014, Sinaga scored a spectacular bicycle kick in a 3-1 win over PS Barito Putera. He juggled the ball twice from a corner kick before unleashing an unstoppable overhead kick into the net.
