Matt Leinart has been released by the Buffalo Bills five days after being signed by the club.
Leinart went just 3-for-10 for 11 yards and a pair of interceptions in Thursday's preseason game.
The Bills needed a quarterback with EJ Manuel sidelined due to a knee injury and Kevin Kolb's career in jeopardy due to another concussion.
"Tough game. Tough situation. No excuses. (Thank) you to the Bills organization!" Leinart wrote Friday, before deleting the tweet.
