Former Ravens linebacker Tyus Bowser has withdrawn his grievance against the team, a source with direct knowledge of the matter confirmed to The Baltimore Sun.

The move comes about a year after the 2017 second-round draft pick claimed Baltimore had misdiagnosed a knee injury that sidelined him for the 2023 season.

In March of that year, the Ravens released Bowser and he filed a $4.5 million grievance against the team the following month.The Ravens were hit with a $1.8 million salary cap penalty as a result and would have faced another one for $2.7 million if Bowser had won his case. But with Bowser withdrawing the complaint, Baltimore will receive a $1.8 million cap credit.

Last October, Bowser, 29, told The Sun that he suffered loose bodies in his knee — fragments of bone or cartilage that break off and float in the knee joint, causing pain, swelling and limited range of motion — and that he later got a staph infection.

“I went the entire year without knowing exactly why my knee was reacting the way it did, and then I go to somebody else [for an opinion] and he tells me within 10 minutes what the problem is,” he said at the time. “Something as simple as an MRI you’ve seen millions of times, you can’t see this simple thing. That’s nobody else’s fault but yours.”

But now, Bowser has apparently backed off those claims.

The Ravens selected Bowser out of Houston in 2017 and in March 2021 signed him to a four-year, $21 million extension.

He went on to have his best season that year, starting all 17 games and finishing with 59 tackles, including eight for loss, seven sacks and two forced fumbles, all career highs.

However, Bowser has struggled to stay healthy in recent years.

In 2022, he appeared in just nine games (four starts) after undergoing surgery to repair a torn Achilles tendon in January of that year.

The following season, coach John Harbaugh expected Bowser to be available by the start of the regular season but he instead spent the year on the non-football injury list and remained with the team throughout, even joining them on a trip to London for the their game against the Tennessee Titans.

After the Ravens released him, Bowser signed with the Seattle Seahawks’ practice squad last August and appeared in two games (one start) for coach and former Ravens defensive coordinator Mike Macdonald.

He was then signed by the Dolphins and appeared in nine games (five starts) for Miami and defensive coordinator and former Ravens defensive line coach Anthony Weaver.

Bowser finished the year with 11 tackles and is currently a free agent.
