"Byron took a whack on the shin and has gone straight to hospital for X-rays, but hopefully it is not too serious," said Trollope. "We don't think there is any break, but we will know more later."
On the game itself, Trollope added: "It was an opportunity missed for us because we dominated territorially and didn't have what it takes in the final third of the pitch to break Tranmere down.
"We need a strategy for when teams come here and defend in numbers against us. Swindon and Millwall had good results so we have lost more ground on the play-off positions.
"Having said that, we remain on a good run and now have a big week ahead with visits to Exeter and Yeovil."
