The Niners didn’t start Garoppolo for their first game of the 2019 NFL preseason — a 17-9 home win over the Dallas Cowboys last Saturday. And while neither backup candidate, Nick Mullens or C.J. Beathard, did much to distinguish himself above the other during the exhibition bout, neither QB hurt his chances much either.
Well, to a point.
Beathard did suffer a thumb injury versus Dallas, which forced him to miss Tuesday’s practice at Levi’s Stadium.
