Aged just 17 Tučkus won the Lithuanian Cup with Eļņias Šiauliai, a year later he won the 3rd place in the USSR youth championship and after just one more year he already played 20 matches for Spartak Vilnius in the Soviet B league.
In 1953 with Tučkus in goal Spartak earned a promotion to Soviet Top League.
[citation needed][1] Because of problems with discipline off the field Tučkus' career seemed finished and by 1960 he was living in Brocēni, Latvia without a job and a perspective.
But then he was offered to return to football and to play for FK Daugava Rīga which in 1960 because of a decision from above had got a place in the Soviet top league.
Tučkus returned to training and soon proved that he still was a very good goalkeeper and it was largely his contribution that allowed Daugava to finish in the middle of the table in 1960.
