HENDERSON, Nev. -- Las Vegas Raiders linebacker Blake Martinez, who joined the team just over a month ago, announced his retirement on social media Thursday.
Martinez, 28, announced his decision four days after leading the Raiders with 11 tackles in this past Sunday's loss to the Jacksonville Jaguars.
"I had an amazing journey with some incredible franchises, and made lifelong friendships," Martinez wrote on Instagram. "I have chosen to step away from this career at this time to focus on my family and future passions! I am excited for this new journey and appreciate all the fans and organizations that have supported me throughout the years!
