The team waived fullback Ray Agnew and re-signed defensive lineman Christian Tupou to the practice squad to make room on the roster for Thigpen.
Thigpen last played in an NFL game in 2012 with the Buffalo Bills. Thigpen, 30, was signed by Cleveland last offseason but was released during training camp.
Cleveland’s top two quarterbacks, veteran Brian Hoyer and rookie Johnny Manziel, are injured. Manziel will not play in the season finale against the Baltimore Ravens because of a hamstring injury, and Hoyer is nursing an injured shoulder and is considered “day to day.”
Browns head coach Mike Pettine said he will see how Hoyer goes through this week in practice before deciding on who starts on Sunday.
The only quarterback on the roster is Conner Shaw, who has been on the team’s practice squad and will get some time with the first-team offense, according to Pettine. The team also reached out to Rex Grossman, but the two sides couldn’t reach an agreement.
Thigpen was mostly recently in the news when he was arrested last month and charged with driving under the influence when he failed field sobriety tests after being found asleep at the wheel at a Wendy's drive-thru in Myrtle Beach, S.C.
