The San Francisco 49ers have sent shockwaves through the NFC with a bold and strategic move, signing veteran offensive tackle Isaiah Prince to bolster their offensive line. This decision comes at a critical time, as concerns swirl around the health of starting right tackle Colton McKivitz, who was conspicuously absent from Saturday’s practice. While the 49ers have yet to disclose the official reason for McKivitz’s absence, head coach Kyle Shanahan is expected to provide clarity during his Monday media session. However, the team’s swift action in signing Prince suggests that McKivitz may be dealing with an injury, prompting the 49ers to reinforce their depth at a pivotal position.
Why Isaiah Prince Is a Game-Changer
Isaiah Prince, a 2019 sixth-round draft pick out of Ohio State, brings much-needed experience to a 49ers offensive line that is dangerously thin at tackle. A former teammate of 49ers star Nick Bosa at Ohio State, Prince has appeared in 22 NFL games with six starts across his tenure with the Miami Dolphins, Cincinnati Bengals, Denver Broncos, and Atlanta Falcons. While he hasn’t started a game since 2021, his experience far surpasses that of the 49ers’ current backup options, making him a critical addition as the team gears up for a rebound 2025 season.
On Saturday, with McKivitz sidelined, the 49ers turned to Austen Pleasants as their starting right tackle. Pleasants, an undrafted free agent, has played just 77 snaps in five career games with no starts, underscoring the team’s lack of depth. Compared to Pleasants, Prince is a seasoned veteran who offers reliability and a proven track record. His signing signals the 49ers’ proactive approach to addressing vulnerabilities and ensuring their offensive line remains a strength as they prepare to compete in a highly competitive NFC.
The 49ers’ Offensive Line Crisis
The 49ers’ offensive tackle depth has been a growing concern, exacerbated by their failure to draft a tackle since 2021. This offseason, the team signed Andre Dillard to serve as a backup, but he has been sidelined by injury and has yet to practice, casting doubt on his roster spot. Meanwhile, Spencer Burford, who played left tackle in college, has been moved back to his original position after primarily playing guard in the NFL. However, his transition has been rocky through the first nine days of training camp, highlighting the 49ers’ desperation for experienced options.
Prince’s arrival couldn’t be more timely. With McKivitz’s status uncertain, the 49ers needed a player with starting experience to stabilize the line. Prince’s familiarity with high-level competition, dating back to his Ohio State days alongside Bosa, makes him a seamless fit for a team looking to maintain its physical, hard-nosed identity.
What This Means for the NFC
The 49ers’ decision to sign Prince is more than just a depth move—it’s a statement of intent. After a disappointing 6-11 season in 2024, San Francisco is determined to reclaim its place among the NFC elite. The offensive line, anchored by All-Pro left tackle Trent Williams, is crucial to protecting quarterback Brock Purdy and powering the team’s zone-heavy run scheme. By adding Prince, the 49ers are ensuring they have the depth to withstand potential injuries and maintain their offensive firepower.
This move puts the rest of the NFC on notice. Teams like the Philadelphia Eagles, with perennial Pro Bowler Lane Johnson at right tackle, and other contenders will now face a 49ers squad with renewed stability up front. If McKivitz’s absence proves to be short-term, Prince provides insurance and versatility. If the injury is more serious, Prince could step into a starting role, giving the 49ers a fighting chance to keep their offensive line intact as they push for a playoff berth.
The 49ers’ signing of Isaiah Prince is a calculated power play that addresses an immediate need while sending a message to the rest of the league: San Francisco is all-in for 2025. With training camp in full swing and the preseason just a week away, the 49ers are making it clear they’re not leaving anything to chance. Whether Prince serves as a stopgap or a long-term solution, his addition strengthens a critical position group and sets the stage for a potential bounce-back season.
As the 49ers await further updates on Colton McKivitz’s status, the NFC is watching closely. This is a team that’s been to the Super Bowl twice in the past six years, and with moves like this, they’re signaling they’re ready to fight their way back to the top. The rest of the conference better buckle up—San Francisco is coming for the crown.
