England great Frank Lampard will have to wait to make his Major League Soccer (MLS) debut after he was ruled out of New York City FC`s match against Toronto FC on Sunday with a calf strain.
Lampard, 37, signed for the newest MLS franchise from Chelsea in July 2014 but spent last season on loan at Manchester City.
The 106-cap England international arrived in America following his Premier League commitments with City but will have to wait to make his U.S. bow after the injury during training.
"I`m hugely disappointed to be missing out on Sunday`s game, which I have been really looking forward to," Lampard told the club`s official website (www.nycfc.com) on Friday.
"I`ve been feeling great in training and have loved working with the squad. Unfortunately I sustained a small strain to me calf during a session.
"The good news is that I should be back in full training next week."
During a glittering 13-year career at Chelsea, Lampard won three Premier League titles, four FA Cups, two League Cups, the Europa League and the Champions League and left Stamford Bridge as the club`s record goalscorer.
Lampard is one of three of New York City`s major close-season signings alongside the arrivals of World Cup winners in Spaniard David Villa and Italy`s Andrea Pirlo.
Former England and Liverpool captain Steven Gerrard is expected to make his Los Angeles Galaxy debut in their International Champions Cup match against Club America on Saturday.
