Sorry—
"Governing. . .is. . .concern." That would be correct. "Governing" is the subject, which has a compound within its phrase (this is a gerund phrase serving as the subject of a sentence), but "governing" is singular; thus the verb and "concern" must be singular also (not "concerns"). This is essential parallelism.
HOWEVER, if the writer intended "Governing the tempo of the match" and "safety of the players" as TWO separate things, the verb would be "are," and "concerns" would be parallel. Yet, that compound subject would be unparallel; thus, "Governing the tempo of the match and MONITORING THE safety of the players" would be standard, with the verb and "concerns" remaining plural.
Strunk and White is interesting, but I suggest STYLE, by Joseph Williams—as S&W has errors and contradictions within its "commands."
