Notts County will be without midfielder Ricky Ravenhill for a fortnight because of concussion.
The 30-year-old was brought off on a stretcher in the first half of Notts' dramatic win over Tranmere after a heavy collision knocked him out cold.
Magpies boss Martin Allen said: "In the level of concussions, in simple terms - level of one to 10 - he's up there at about an eight.
"I didn't like seeing my player like that," he added.
Allen refused to blame the Tranmere players in his post-match comments, though says he was upset to see his player in such distress.
"Just thank God he's OK as a human being and as a dad and a husband. That's the most important thing to me," he said.
"That's more important than being a footballer or a football manager or trying to win a game of football."
