The Jacksonville Jaguars' backfield entered the early part of the week dealing with injuries and in need of help.
"Jamaal, he looked good. He looked in shape; he looked like he was ready to go ... We need some help, so we brought those guys in here. We'll just put them to work."
While the full realm of his responsibilities remains unknown, Charles said he will do whatever the coaching staff asks of him and he doesn't believe it will take long to pick up the playbook, pointing out his experience on two different teams.
"I've been a vet for years now, I mean, for a decade at least, so now football is like football to me," Charles said.
Meanwhile, the Jaguars are likely to stick with Yeldon in the lead role until Fournette returns even if Charles acclimates quickly.
At this stage of his career and with a history of knee injuries, Charles provides a veteran presence and can help out in a complementary role as a situational running back.
