The Patriots announced the release of running back Tyler Gaffney on Monday.

Gaffney has not been able to stay healthy. A sixth-round pick of the Panthers in 2014, Gaffney was waived-injured by the Panthers after suffering a knee injury and claimed by the Patriots, who saw adding Gaffney as a low-risk transaction.

He spent 2014 on injured reserve with the Patriots and got hurt in training camp last year. He was waived-injured by the Patriots and after going unclaimed, he landed on injured reserve.

Gaffney ran for 1,709 yards and 21 touchdowns at Stanford in 2013.
