Akin Famewo returns to the starting lineup for the first time since December and Lee Bowyer has handed a full debut to Matt Smith for today’s trip to Fleetwood Town.
Ronnie Schwartz and Ian Maatsen also return to the side with Bowyer making four changes from the team that played Gillingham last weekend.
If the Addicks start in the same 4-4-2 formation used in recent weeks then Chris Gunter, Deji Oshilaja, Famewo and Maatsen will make up the back four in front of Ben Amos. Smith will likely partner Darren Pratley in midfield with Liam Millar operating from the left and Andrew Shinnie on the right behind the front two of Schwartz and Jayden Stockley.
Nathan Harness, Albie Morgan, Ben Watson, Diallang Jaiyesimi and the returning Conor Washington join Purrington and Pearce on the Charlton bench.
Charlton: Amos; Gunter, Oshilaja, Famewo, Maatsen; Shinnie, Pratley (C), Smith, Millar; Stockley, Schwartz
Subsitutes: Harness, Pearce, Purrington, Morgan, Watson, Jaiyesimi, Washington
