The 49ers placed Ricky Pearsall on injured reserve Saturday and one of the players in position to help replace him on offense is out of practice with an injury.
Rookie De'Zhaun Stribling is not practicing because of hamstring tightness. The 49ers said, via multiple reporters, that Stribling is not dealing with a strain.
In addition to losing Pearsall with a PCL injury, the 49ers have been practicing without veteran Christian Kirk. Kirk has missed several days with a calf injury.
Stribling was the first pick of the second round this year and his early work has earned rave reviews from quarterback Brock Purdy. A brief absence probably wouldn't alter plans for him to play a role right out of the gate, but any extended time off the field would work against an early impact for the rookie.
