Mike Davis, who suited up as a running back for six teams across eight NFL seasons, announced his retirement on Monday.

Davis, who did not play in 2023, took to social media with a message of gratitude on his 31st birthday.

"As I turn 31 today, I sit back and look on my NFL career and how thankful I am to be apart of a brotherhood," he wrote. "This game has allowed me to make a lot of friends and memories. I'm grateful for every organization in NFL. With that being said I'm retiring!"

Davis broke into the league as a fourth-round draft pick in 2015 by the San Francisco 49ers.

In 87 career games (30 starts) for the Niners (2015-16), Seattle Seahawks (2017-18), Chicago Bears (2019), Carolina Panthers (2019-20), Atlanta Falcons (2021) and Baltimore Ravens (2022), Davis amassed 2,052 yards on 3.7 yards per carry with 14 touchdowns. He also collected 171 receptions for 1,066 yards and four receiving touchdowns.

He started 12 games for the Panthers in 2020 (15 total appearances) and posted career bests of 642 rushing yards, six touchdowns, 59 catches, 373 yards and two touchdown receptions.
