Running back Carlos Hyde sustained a hip injury in the first quarter Sunday, was on the sidelined for most of the period, but returned later in the game and scored his first touchdown of the season.
His early absence had a big impact later in the opening quarter when one of Hyde's backups, Raheem Mostert, fumbled during a promising 49ers drive and the Rams took over at their own 39-yard line.
That was a theme in the first half: When Brian Hoyer was intercepted on the first snap of the game, the Rams scored on a short Todd Gurley touchdown run on the next play.
Et cetera -- Brian Hoyer's nine-yard touchdown in the first quarter was his first since Oct. 18, 2009 when he was a rookie and Tom Brady's apprentice with the New England Patriots.
* Linebacker was on the sideline in sweat pants but without a walking boot on his injured right ankle, a sign that he is recovering well from the injury.
