OWINGS MILLS, Md. -- Baltimore Ravens coach John Harbaugh created a stir in the fantasy football world last week when he spoke about his expectations for rookie running back Kenneth Dixon.

"I would love to see Kenneth Dixon on the field more," Harbaugh said.

How much of an increased workload can one project for Dixon? Expectations should be tempered. Under Harbaugh, the Ravens have rarely relied on a rookie running back.

Ray Rice averaged 10.7 touches per game in his first NFL season in 2008. Buck Allen never received more than 10 touches in a game as a rookie last season before Justin Forsett suffered a season-ending injury. No other rookie running backs got more than 115 touches for Baltimore.

That's why it would go against the Ravens' track record to put the running game on the shoulders of Dixon. But it's reasonable to project more than a handful of touches for him, which has been the case in his first three games.

Dixon, who missed the first four games with a knee injury, is getting healthier. He will earn more playing time if he can improve in pass protection.

In Baltimore's two practices during the bye, Dixon ran with the starters because Terrance West was nursing an ankle injury.

"Kenneth Dixon looked even more juiced up," Harbaugh said after one of the practices.

West has earned the right to remain the featured back for now, averaging 76.2 yards rushing since becoming the starter the past four games. But West's injury could be a sign that the Ravens need to split up some carries in order to reduce wear and tear for their backs.

Asked if plans to give one back the majority of the touches, Harbaugh said, "To me, that debate will be ongoing."

Dixon has not made much an impact yet, totaling 10 yards rushing on six carries and six yards receiving on three catches. The excitement surrounding Dixon comes from the summer, when he was the team's most explosive back. In the preseason, he averaged 4.9 yards on 22 carries.

"If [Harbaugh] wants me to get a better workload, I'm definitely prepared for it," Dixon said.
