“In the face, around the eye, I have three minor fractures in the bones, which fortunately do not require surgery.
“In addition I have broken three ribs and a punctured lung.
“And in the end I have a small hemorrhage in the brain – nothing serious, the doctor said.
“What’s going to happen from here, I’m not sure yet.
“Going to do my best to get back in shape and see where this takes me in the future.
“I want to race again because it’s what makes me happy and feel alive.
“I really thought I had everything under control at this time. But getting hit from behind is hard to avoid.
“This is a race accident and I have no grudge against Lawson – I know this could happen.

“All the focus now is on getting back in shape.
“Thank you for all the love and support.”
Plymouth Gladiators also posted an update, which said: “At this stage, the focus is on his recovery. While the full timeline remains unclear, Tobias is determined to work hard to regain full fitness and assess his options moving forward.
“Racing is something he loves and is a huge part of his life, and his aim is to return when he is ready.
“Finally, a huge thank you to everyone who donated last night. An incredible £1,387.95 was collected in the buckets, and your support is hugely appreciated.
“Thank you also for all the messages of support they mean a great deal and Tobias will see them.”
