Answer:
Yes, this is a proper use of a semicolon.
Explanation:
"However" is a conjunction adverb used to express contrast. When placed between two independent clauses, it should be preceded either by a semicolon or by a period. Just a quick reminder, an independent clause is a group of words containing a subject and a predicate that is able to express a complete thought on its own.
Take a look at the examples below:
- Ted invited me for the party. However, I did not want to go.
- Ted invited me for the party; however, I did not want to go.
With that information, we can clearly see that the semicolon used in the sentence "It's finally time for the big tournament; however, the team's coach has some bad news" is correct.
