Uncertainty hangs over greenwood as career left in tatters

It sounds like you're referring to a sports player, specifically a footballer, who is facing an uncertain future due to a career-threatening injury or a series of poor performances. Here's a rewritten version with a more formal tone:

"Uncertainty surrounds the career of Greenwood, whose prospects appear to be in tatters following a string of disappointing performances and a lingering injury concern. The talented footballer's future is now shrouded in doubt, leaving fans and pundits alike wondering if he will be able to regain his form and secure a place in the team."

Would you like me to rephrase anything or provide more context about the situation?
