The New England Patriots have issued an unrestricted free agent tender to LeGarrette Blount, according to a league source.

The tender, which is seldom-used, means that if Blount remains unsigned past July 22, he can only play for the Patriots next season.

If he signs before that date with another team, Blount would count toward the 2018 compensatory draft pick formula.

The tender had to be extended by May 9.
