Ruben Loftus-Cheek is set to return to Chelsea training within 'four to six weeks' after being sidelined since May with a ruptured Achilles.
The England international sustained the injury during the Blues' friendly against New England Revolution, which caused him to miss the Europa League final against Arsenal.
Despite not turning out for Lampard, Loftus-Cheek has been handed a new five-year deal worth £150,000-a-week in July, with the club demonstrating faith in the midfielder to return to the form that earned him regular call-ups to the national squad.
Since breaking into the first-team at Stamford Bridge at the beginning of last season, Loftus-Cheek has scored ten goals in 40 appearances in all competitions, having registered just two in the 32 prior. He had a loan spell at Crystal Palace for the duration of the 2017/18 campaign, where he shot to attention with some dazzling displays for the Eagles.
His return will provide Lampard with a major boost when he's back to full fitness, while another player set for an injury comeback is Callum Hudson-Odoi.
The 18-year-old winger has been out of action since April 22 after suffering an Achilles injury against Burnley, but the forward has since returned to training along with the rest of the squad as he aims to rediscover his match fitness.
News of Hudson-Odoi's return to senior training looks set to coincide with the youngster signing a new five-year deal at the club, which looks set to make him the highest paid teenager in world football with earnings of £200,000-per-week.
