49ers injury concerns and a reported NFL probe of a viral Trey McBride exchange

Bleacher Report, citing ESPN’s Adam Schefter, reports that the NFL said it was investigating an exchange between an official and Cardinals tight end Trey McBride. NFLPA executive director JC Tretter called the official’s behavior unacceptable. Separately, a 49ers account praised Mike Evans for playing through a rib injury and relayed Kyle Shanahan’s view that “Juice” might have a knee sprain; it said initial signs suggested his ACL was intact.
