Derek Anderson informed the NFL of his intention to retire last week.
Anderson spent part of last season with the Buffalo Bills, serving as a mentor to rookie Josh Allen and appearing in two games.
Anderson, who turns 36 next month, had re-signed with the Bills after the season but indicated recently to the team that he was thinking of retiring.
He took to Twitter on Monday to thank those who helped his career, noting "it took a village."
Here is Anderson's message:
Well here we are. I was just a guy. But still it took a village to help me thru this journey. The teammates, coaches, staff, trainers, eq, friends and most importantly my wife and family. But it’s made me who I am today! So @Ravens @Browns @AZCardinals @Panthers @BuffaloBills .. pic.twitter.com/iDlNSPmg1v
