Chelsea captain John Terry is undergoing platelet-rich plasma therapy in an effort to recover from injury before the end of the season.

The 35 year-old has missed his side's last two Premier League games after aggravating an Achilles injury.

The Blues skipper, who is out of contract at the end of the current campaign, has only recently recovered from a long-term hamstring problem.

Despite the plasma therapy, Terry is still expected to remain sidelined for at least another two weeks.

The former England international took to Instagram to post an image of himself undergoing a session of therapy.

"Being injured is the most frustrating thing as a player. Working hard to get back fit," he wrote.

The practice was prohibited by the World Anti-doping Agency (WADA) until 2011.
