Leyton Orient have suffered a fresh injury blow as Josh Koroma is expected to miss three to four weeks with a hamstring injury.

The forward hobbled off less than five minutes into the second half of the 3-0 win over Maidstone United on Saturday, pulling up completely unchallenged as the ball went out of play, and was replaced by Matt Harrold.

The 20-year-old, who has scored nine goals this season, has suffered a grade two hamstring injury.

Meanwhile, injured trio Josh Coulson, Marvin Ekpiteta and James Dayton remain a few weeks away from a return to action.
