Running back Montee Ball, who was arrested after a weekend altercation with his girlfriend, had been signed to a futures contract by the Patriots before the team released him, ESPN.com reported on Tuesday.
The Patriots filed the paperwork with the NFL Feb. 1, but did not announce the Ball signing.
Prosecutors charged Ball with disorderly conduct, a misdemeanor, for an incident at a downtown Madison hotel early Friday. The woman told police she and Ball were arguing when he threw her in the air and she landed on a table, cutting her leg.
A criminal complaint says Ball also was charged with misdemeanor battery for allegedly striking the woman on the face five days earlier.
The Patriots had signed Ball to their practice squad Dec. 15. Ball was released by the Broncos in September.
