The 29-year-old joins the Rebels on non-contract terms and is available for selection for tonight’s match away at Hampton & Richmond Borough.
The former Ireland U21 international left Premier League outfit Luton Town by mutual consent last month, ending a seven-year association with the Hatters where he made 207 appearances.
During that time Rea was part of the Luton teams that won promotion from League Two and League One, also helping them establish themselves in the Championship in the 2019/20 season.
After making just 13 appearances for the Hatters in the first half of the 21/22 season, Rea linked up with Wigan Athletic on loan in January 2022. Unfortunately, his spell was cut short after suffering a knee injury during the Latics’ 1-0 win over AFC Wimbledon that season.
After missing nearly a year of football, Rea continued his rehab in the second half of last season on loan at Cheltenham, helping the Robins avoid the drop in League One.
Rea was born in Brighton and began his career with the Seagulls, signing his first professional contract in 2013. He made his debut for the Seagulls in 2015 before loan spells with Southend United and Luton Town, who he joined permanently in 2016.
Rea will wear the squad number 31 for the Rebels.
