BOX SCORESANTA CLARA — The 49ers’ healthy regulars participated in the joint practice Tuesday against the Tennessee Titans.
That was their work for the week. At least, that’s how 49ers coach Kyle Shanahan saw it.
All the recognizable 49ers were spectators Thursday for the preseason opener, as the Titans never trailed in a 19-13 win at Levi’s Stadium.
Shanahan was on the sideline, as usual. He continues to make progress from a concussion he sustained on July 14 in a car accident in Palo Alto. He turned play-calling duties over to offensive coordinator Klay Kubiak.
Shanahan opted to use the first dress rehearsal of the summer to evaluate the young players and veterans fighting for spots on the regular-season roster.
First-year Titans coach Robert Saleh took another approach. Tennessee is coming off a 3-14 season. Brian Callahan was fired after just six games last season, which opened the door for the former 49ers’ defensive coordinator to take on the rebuild.
It was good work for the 49ers youngsters, as they went up against the Titans starters for most of the first half.
