Stevenage's Greg Tansey has undergone groin surgery.
The midfielder, 24, has been struggling for fitness for some time and has now gone under the knife in a bid to clear up the problem.
Tansey looks set to miss Boro's next few matches, starting against Portsmouth on Saturday, but he hopes to be back before the end of the season.
He wrote on Twitter: "Surgery went well, a bit sore but hopefully get back before the end of the season. Thanks for all the support."
