The midfielder - back from knee surgery - covered every blade of grass against a strong Charlton outfit at The Valley.
In only his second comeback game, Sean was bombing up and down from the first to last whistle in the somewhat harsh 2-1 defeat against the Barclays Premier Reserve League leaders.
Development coach Clive stated: "Sean looked stronger and stronger as the game wore on and that's all credit to the hard work he's put in and the medical staff who have worked with him.
"He needs games and that was a good game for him. He knew that.
"You saw in flashes what he's about. He controlled the ball well, linked play up and it was a solid performance from him. He will only get better for it."
Clive Allen praised the work ethic of Sean Davis after his first 90-minute stint since October for the reserves on Monday night.
