49ers place 4 players on the active/PUP List; sign former 6th-round tight end

San Francisco 49ers general manager John Lynch announced a series of moves Saturday morning. The Niners waived undrafted rookie tight end Khalil Dinkins with a non-football injury. Taking his roster spot will be tight end Tanner McLachlan, a 6th-rounder from the 2024 NFL Draft out of Arizona.

McLachlan is a big body at 6’5 1/8″, with surprising speed. He ran a 4.61 40-yard dash, which is in the 87th percentile. His 10-yard split of 1.58 was in the 84th percentile. McLachlan was most recently with the Bengals.

Defensive tackle Evan Anderson will be released at some point on Saturday. Lynch said there will be a corresponding move, although that hasn’t been announced yet.

The following players will begin training camp on the active/PUP list:

TE George Kittle (Achilles)
RB Isaac Guerendo (pec)
DL Mykel Williams (ACL)
DT Alfred Collins (shoulder)

Lynch said, “George’s rehab is coming tremendous. I know you guys have heard from him. He’s doing really well. That’s very exciting. He’s doing everything possible to be ready for Week 1. We’re thrilled with his process.”

For Williams, Lynch said, “What I would say with Mykel, he’s making every effort to be ready for Week 1. We’ll see if that’s a reality. We’ll let the markers and the medical staff kind of dictate that out.”

As for Collins, the 49ers are expecting him back in “the second window. Don’t hold us to that, but that’s the plan right now. If he keeps hitting the markers, that’s about when Alfred will be back.”

Players placed on the PUP list before training camp count as part of the 90-man roster. However, they cannot practice until they’re physically cleared and removed from PUP. Since the four players are on the active/PUP List, they can be removed from the list at any point during training camp.
