Arsenal forward ruled out for at least six months - producing a variety of responses among supporters.
After Theo Walcott received good news and terrible news on the same day, many took to Twitter to express their reactions.
The winger was told there will be no further action over his gesture to Spurs supporters in Saturday's FA Cup tie, however he was also given the devastating news that the injury that saw him stretchered off in front of those fans would rule him out for six months, meaning he'd miss the rest of the Premier League season AND the World Cup in Brazil.
A statement on the Arsenal website read: "Theo has sustained a ruptured anterior cruciate ligament of his left knee.
"He will have surgery in the near future and is expected to be out for at least six months, thus missing the rest of the season and the World Cup."
With Arsenal sitting at the top of the Premier League, and Walcott having made such an impression since returning from injury in November, the loss will be keenly felt at the North London club.
His five goals in eight appearances also indicated that Walcott would play a key role in England's World Cup challenge in the summer.
Arsene Wenger will now surely be tempted to dip into the transfer market given other injuries to his forwards, while Roy Hodgson will have to look for alternatives to the speedy attacker.
Inevitably people took to Twitter, both of Arsenal and Tottenham persuasion. Many wished the former Southampton man a speedy recovery, but there were some that felt the banter between Walcott and Tottenham could be taken to a new level.
Here are a selection of some of the varying views:

This is the second World Cup he won't play in! Really feel for Walcott— Pushpa T (@TPushpa) January 6, 2014
With Walcott's game heavily reliant on speed, you do wonder what impact this injury will have long term. Michael Owen springs to mind.— Imaad Bajwa (@Iddy234) January 6, 2014
