Hello KillerFishes,
While such a fish can sometimes still shove with even just Qx or maybe even weaker straights this Call should be doable. Although I would very often expect him to have at least straight there, but could as well be that he has been slowplaying FH, sometimes I might even prefer just folding directly while we haven't invested that much into to pot but while we have 2card straight, you can consider Calling it.
Best regards.
