FORMER QPR duo Lee Cook and Martin Rowlands are in the O’s squad to face Everton in the Capital One Cup on Wednesday evening.
The midfield pair signed for the east Londoners on short-term contracts in the last week and could both make their debuts at Goodison Park.
Winger Cook spent two months on loan at Brisbane Road from the R’s last term, while Rowlands left Colchester United in the summer after moving to the Essex side from Rangers midway through last season.
Slade will also have Kevin Lisbie back after the striker missed last Tuesday’s defeat to Stevenage with a tight hamstring.
Scott Cuthbert is facing two months on the sidelines with his hamstring injury, while Lee Butcher remains out with a long-term knee problem.
