England bowler Chris Woakes will miss the remainder of the Champions Trophy with a side strain he picked up in Thursday's tournament opener against Bangladesh, the England and Wales Cricket Board (ECB) said.
"A scan has confirmed that Chris Woakes sustained a left side strain in yesterday's ICC Champions Trophy match against Bangladesh," the ECB said in a statement on Friday.
"The injury means Woakes will miss the rest of England's participation in the Champions Trophy."
The 28-year-old bowled just two overs before leaving the field as England cantered to an eight-wicket victory after chasing down a victory target of 306 with 16 balls to spare.
"An update on a replacement for the seamer for the remainder of the tournament will follow in due course," the ECB added.
Root also suffered an injury scare when he damaged his calf early in his innings but he made light of the problem to post his highest one-day international score.
"It's all right - it looks like it's just a bit of cramp," Root said.
"I must not have eaten well enough this morning. I don't see it as too big an issue."
Opener Alex Hales made 95 and Morgan's 75 not out steered his team to victory with Root as England began their bid to win a first global 50-over title.
"Obviously, Alex continued his form," Morgan said. "Joe, unbelievable, as usual, and it was nice for me to get some runs as well."
The major disappointment for England was another failure for opener Jason Roy, who was caught at short fine leg for one to continue his poor run and intensify the calls for in-form Jonny Bairstow to replace him in the side.
Morgan, however, said Roy will keep his place in the team for England's next match against New Zealand in Cardiff on Tuesday.
"I thought he (Roy) was terribly unlucky today," Morgan said.
"It was quite smart, bowling a slow ball, and brave ... a big gamble. That sort of stuff can happen. You can get out in that sort of fashion when you're short on runs. But, yes, certainly we believe in him."
