Paul Connolly has had his contract with Luton Town cancelled with immediate effect.
The 31-year-old joined the League Two side last summer following his release by Crawley Town.
He made his debut on the opening day of the season, but since then he has been restricted to just five more appearances in all competitions, the last of which came back in January.
The right-back started his career with Plymouth Argyle, before having spells with nine other clubs.
