PLEASE DON'T TELL ME THAT YOU "PRACTICE SPORT"!
Many Spanish people use the phrase: "I like to "practice sport" at the weekend". This is SPANGLISH TOTAL! Instead you need to say: "I like to do sport at the weekend".
If you want to be more specific you need you use "play": "I like to play tennis at the weekend" (there are some exeptions, of course, like swimming and running). The word "practice" is used more in connection with an instrument: "Every day I practice the piano".
Hope that helps!
