Daniel Thomas on roster bubble

Dolphins running back Daniel Thomas has not played in the first three preseason games and knows he's in danger of getting cut, reports the Palm Beach Post. Thomas, who will play Thursday against the Rams, said he feels he has a lot to prove.

"I haven't been out there in a while," he said. "I just want to show coaches that my hamstring is good. I feel good and I'm ready to play good."

Behind Lamar Miller and Knowshon Moreno at running back, the Dolphins have impressive undrafted rookie Damien Williams. To make the team, Thomas might need Miami to keep four running backs, the paper said.
