Ray Lewis and Derek Jeter are both the longtime leaders of their respective teams, and now both are out until next year. Which player's injury is more significant?

The Baltimore Ravens defense has been centered on Ray Lewis since the late '90s, and his performance has led to a stunning run of success, including one Super Bowl victory. He tore his triceps on Sunday, which has everyone wondering whether his team will be able to operate without him. The injury may even be a career-ender, though Lewis claims he will be back for his 18th season next year.

Derek Jeter also suffered a major injury, a fractured right ankle, which will keep him off the field until spring training. It's unlikely to end his career, but at the age of 38, who really knows?
