Robbie Simpson has committed his future to Leyton Orient by signing a new deal at the Matchroom Stadium.
The striker joined the O's in November on a two-month contract, which was due to expire in the near future.
However, the 28-year-old will now remain with the League One side until at least the summer.
"I'm very happy, I've enjoyed my time here, I've settled in and built a relationship with the players, staff and everyone around the club and I'm pleased to continue that," he told the club's official website.
"I want to keep on getting sharper, I feel like I've been a bit sharper every time I've played and hopefully my luck will change in front of goal! On another day against Carlisle I might have had a hat-trick but I know I need to start chipping in with goals now as well and the ultimate goal is promotion for the football club.
"There's more to come from me. When I first came it was pretty clear that I wasn't match fit but I knew that would improve and it has, and now I feel my performances are up to a level nearer where they should be I just need goals now as at the end of the day that's what strikers are judged on."
Simpson is yet to score in any of his 11 outings for Orient.
