The Patriots signed three players who tried out for the team during rookie minicamp and released one undrafted free agent in a corresponding roster move.

The Patriots signed defensive tackle Isaiah Iton, who was with the Titans last season, and rookie free agents guard Mehki Butler and defensive tackle Wilfried Pene.

The Patriots released tackle Cole Birdow, who signed as an undrafted free agent on Friday.

Pene, who’s from France and played at Virginia Tech, does not count against the Patriots’ 90-man roster because they’ll get an international exemption for the 24-year-old defensive lineman’s spot.

Iton, 23, spent his college career at Ole Miss and Rutgers. Butler, 24, played collegiately at Arkansas State and Iowa Western Community College.

Birdow, 24, was a local product, finishing his college career at Merrimack after transferring from Old Dominion.
