Charlton boss Karl Robinson is unsure about the severity of Arsenal loanee Stephy Mavididi’s hamstring injury.

The winger, who arrived on loan last month, was forced off with the problem in the 69th minute.

Mavididi suffered a season-ending hamstring injury last season, which kept him out of action for several months.

And Robinson does not know how long the attacker will be sidelined for this time around. 

He said: “It was his hamstring. I wasn't going to take any risks. There’s no timeframe on how long he’ll be out for.”

Mavididi has been in fine form since re-signing for Charlton, scoring two goals in four league games.
