John Harbaugh has signed a three-year contract extension to remain as head coach of the Baltimore Ravens.

Harbaugh had been about to enter the final year of the four-year deal he signed in 2019.

The Ravens failed to make the playoffs in the 2021 season, finishing bottom of the AFC North on 8-9, and losing all of their last six games of the regular season.

However, it was only their second losing season since winning the Super Bowl under Harbaugh in 2013, when he beat his brother Jim and the San Francisco 49ers in New Orleans.

Harbaugh arrived in 2008 to replace Brian Billick, with the 59-year-old boasting an overall regular-season record of 137-88.

It was also acknowledged by many that the Ravens' poor end to 2021 – having been 8-3 after Week 12 – was heavily influenced by bad luck with injuries.

Ravens owner Steve Bisciotti revealed the news at the annual league meeting on Tuesday, 

"I think John's grown and grown and grown," he said. "It's kind of interesting. I don't feel like I'm just signing up the same guy. I think that's really a compliment to him.

"I really feel like there's a rebirth in John as the years go on. Things that mattered to him don't matter as much anymore.

"I'm just thrilled as an owner to have a guy that's going to be going into his 15th year. So, I'm pretty pleased with it."

Harbaugh is now under contract through the 2025 NFL season.
