Beevers joins Andy McMillan as player-coach and assistant-manager respectively at the Impact Arena.
Thirty-four-year-old Beevers had only signed for the Reds` league rivals Gainsborough Trinity in early Janury.
Injury-hit Beevers signed for Trinity having re-joined Lincoln City in May 2015.
He made nineteen appearances last season but was awarded a benefit match by the Imps in July against Walsall after the popular defender was forced to quit full-time football after suffering a ruptured patella tendon during the 2-0 victory over Boreham Wood in October 2016.
In his first spell, Beevers made 175 appearances for the Imps in all competitions between 2005 and 2009.
The former Welsh under-21 international initially joined Lincoln on loan from Boston United in February 2005 before the move was made permanent with the former Ipswich Town youngster joining for an undisclosed fee.
A successful 2006/07 campaign saw Beevers named as the supporters’ player of the season, and he spent a further two years with the Imps before joining Colchester United.
Injuries restricted his playing time there and he subsequently joined Mansfield after a year with Walsall before helping Stags win the Conference (National League) and re-establish themselves back in the Football League.
