Panthers star Lewis Blackbird was released from hosital last night (May 25) following his crash in the afternoon meeting against Plymouth.
Initial fears of a broken jaw in the wake of his heat nine smash during a 46-44 KO Cup first round, first leg victory at the East of England Showground proved to be unfounded.
But Blackbird did break two fingers in the fourth-bend spill and also suffered concussion.
He is also experiencing back, rib and groin pain, but none of those problems are thought to be serious.
Team boss Carl Johnson said: “I’ve been to visit Lewis and the outlook is a lot brighter than we all feared a few hours earlier.
“He has broken the ring finger and little finger on his right hand, and the doctors are suggesting he will probably be out for between four-to-six weeks.
“But knowing Lewis, and knowing the fact the British Final is three weeks today, I’m sure he will be desperate to return sooner.”
Panthers are back in action on Friday when they host Berwick in the Premier League, but they don’t then race again for another fortnight.
