In a sentence when subject is separated by a comma, we use there plural verb or singular verb? There are no conjunction like and, as well as in between. Like I have one sentence as :
Too much cricket, too many teams to lead have/has left Dhoni jaded.
Here Dhoni is the name of a person.
I think have would sound more appropriate in this context as here comma denote and implicitly. But I am not sure. Please clear up my confusion about it.

Although the conjunction (and) is not explicit, it is understood. There are two simple sentences combined into one. So the verb will be plural.
Hence, all of these demands taken together have reduced the ability of M S Dhoni to perform at his best.
