The 49ers Signed A Center Off Friday's Tryout Sheet And It Cost Them Nick Zakelj

San Francisco signed offensive lineman Doug Kramer Jr. to a one-year deal Monday morning and released offensive lineman Nick Zakelj. The club announced both in the same release, posted to its own transaction log at 10:00 a.m. PT, and it did not leave the reason to be inferred: "In order to make room on the roster, the team released OL Nick Zakelj."

That sentence is the whole mechanism, and the log behind it says the same thing five times.

Ten days, ten in, ten out#

The club's transaction page carries five entries for August, and every one of them balances.

August 1: signed Deebo Samuel Sr. to a one-year deal, placed Ricky Pearsall on the Injured Reserve list. August 2: signed Khalil Herbert and Titus Leo to one-year deals, waived Eli Apple, waived/injured Mikail Kamara. August 5: signed KhaDarel Hodge and Ogbo Okoronkwo to one-year deals, waived Kevin Givens and Cameron Sample. August 6: signed Kion Smith to a one-year deal, waived Colton Dowell. August 10: signed Kramer, released Zakelj.

Ten men in, ten men out, across five club releases, and not one of those releases adds a body without subtracting one in the same paragraph.

A roster at its ceiling behaves exactly like this, and the club has now said so in its own words rather than leaving the arithmetic to be reconstructed. The 90-man limit is not a soft target in August. It is the reason a tryout in Santa Clara on Friday costs somebody his job on Monday.

The verb is different this time#

Four of those five subtractions used the word waived. Zakelj was released.

The distinction is not decorative. A waived player goes onto the waiver wire and can be claimed by another club before he reaches free agency. A released player is free immediately and can sign anywhere. Which word the club used decides where Zakelj spends this week.

The complication is that the two public logs do not agree on what the club has been doing. San Francisco's own page says it waived Apple on August 2 and waived Givens and Sample on August 5. ESPN's transaction file for the same club says it released all three. Three names, two logs, opposite verbs, and no way to settle it from the outside without the league's own wire entry for each man.

ESPN's file, read Monday afternoon, does not carry the August 10 move at all. It stops at August 6. The club's page had it at 10:00 a.m.

Zakelj had an elbow three days ago#

Friday's injury list on the offensive line ran four deep: Vederian Lowe with a high ankle sprain, Carver Willis in concussion protocol, Brett Toth with something nobody agreed on, and Zakelj with an elbow. Nothing published since says the elbow resolved, and nothing published Monday mentions it.

That matters because of which verb the club reached for. A hurt player waived/injured goes to injured reserve if he clears, which is the path William Bradley-King took in July before settling with the club on August 7. A hurt player released outright takes no such path. San Francisco used the injury route four times in the last two weeks and did not use it here.

Whether Zakelj is healthy is the fact that would explain the difference, and it is the one fact nobody has published.

He was the 187th pick of the 2022 draft out of Fordham, where the club's own biography has him in 37 games on the offensive line between 2017 and 2021, and he leaves San Francisco with 29 games and two starts in four seasons, three of those appearances coming off the practice squad last year. All of that is the club's own accounting of him, published in February when it re-signed him. He signed that one-year extension on February 18. It was 173 days ago.

Kramer went twenty picks later in the same round#

Chicago drafted Kramer 207th overall in 2022, twenty selections after San Francisco took Zakelj and in the same sixth round of the same draft. The 49ers replaced their own 2022 sixth-round lineman with somebody else's.

He is 28, from Hinsdale, Illinois, and he started 48 games at center for Illinois between 2017 and 2021. The club lists him at 6-2 and 300 pounds and credits him with 18 NFL games across Chicago, Arizona and Seattle. Pro Football Talk reports his last regular-season appearance came in 2024. The club's own biography places him with Chicago in 2022 and again in 2024 and 2025 and with Seattle in 2025, which is a roster history rather than a snap history; he was on Seattle's practice squad from November 20 to December 2 last year.

Eighteen games in four seasons is a backup center's record, and a backup center is the job that was open. Jake Brendel starts, Toth has been the answer behind him, and Toth has been hurt. Kramer was one of three centers the club looked at on Friday, all three of them centers on a day the team held a walk-through and did not practice.

What would break the pattern#

Cut day is August 30, and between now and then the roster gets cut from 90 to 53. The pattern above is testable in the meantime and it is not guaranteed.

If the ceiling is really what is driving these releases, every addition through August 30 arrives with a subtraction attached to it in the same club announcement. The way it breaks is quiet: the club places a man on injured reserve or the physically-unable-to-perform list on a Tuesday, banks the room, and signs somebody on a Thursday without cutting anyone. That is a legal and ordinary thing to do, and the preseason opener against Tennessee on Thursday is exactly the kind of event that produces the injury to do it with.

Watch the announcements rather than the roster page. The roster page has already shown this month that it does not record every move that happens to a 49er.
