Since taking over as Kansas coach, Charlie Weis has removed 29 players from the Jayhawks team.
That number is back down to 27. Miller was one of 10 players removed from the team in January 2012, despite rushing for 559 yards and four touchdowns on just 136 carries as a freshman in 2011.
He has signed a grant-in-aid offer from Kansas after attending community college in 2012, where he did not play football. Miller will be a redshirt sophomore with three years of eligibility remaining.
Defensive back Dexter McDonald also rejoined the Jayhawks this spring after playing football at junior college in 2012.
In a statement, Miller said Weis is giving him an opportunity to rejoin the team with "stipulations" that were not specified.
"When I left Kansas after the 2011 season, I was in good academic standing," Miller said. "I was dismissed for off-the-field issues that I take full accountability for. I made mistakes as a freshman that not only led to my dismissal, but hurt the Kansas football team. I regret this happened, but I have learned a great life lesson during this ordeal."
Last week, Kansas added receiver Nick Harwell, who was dismissed from Miami (Ohio) earlier this month.
"We constantly research special situations concerning transfer students. Each situation is unique. Occasionally through our due diligence we find a player who fits," Weis said in a statement. "This was the case with both Darrian and Nick. We believe both young men are prepared to thrive at Kansas on and off the field."
