Andy Ritchie had signed Lucas on trial before he was shown the door in November but Davey saw the potential in the 29-year-old keeper and snapped him up on a free transfer. He follows yesterday's signing Grant McCann to Oakwell in the window.
Lucas has played for Preston North End and made a total of 150 appearances between 1994 and 2003. He then joined the Reds arch-rivals Sheffield Wednesday on loan and made 18 appearances during the 2003-04 season. He joined the Owls permanently in 2004 and made a further 62 appearances. He left Hillsborough last May having clocked up 80 appearances.
Lucas is eligible for Saturday's FA Cup trip to Roots Hall to play Southend United and will challenge current first choice keeper Nick Colgan for a first team spot.
Meanwhile The Reds have also been linked with Aberdeen defender Russell Anderson. According to Yahoo Sport Reds scouts were in the crowd in Aberdeen's 0-0 draw with Hibernian. The fact that Portsmouth, Middlesborough and Everton have also had people watching could end any hopes of him coming to Oakwell.
David Lucas is the Reds' newest addition
