Titus Till and Jeremiah Wilson both left Maryland for James Madison after Randy Edsall's first year as the Terps' coach in 2011.
Both will return to College Park on Saturday when Maryland hosts James Madison.
Till was a four-star recruit when he signed with the Terps in 2010 and has been a starter for the Dukes the past three years.
Till was a strong safety his first two seasons, but new James Madison coach Everett Withers said Till will play linebacker as a senior this year.
He ranked fourth on the Dukes with 62 tackles last season.
"He's been a really good player for us though spring and our offseason and also through camp," Withers said during a conference call Monday. "We expect him to be a big part and a big piece of our defensive football team."
Wilson is a starting cornerback.
He has missed eight games due to injury the last two years, but he had 35 tackles and a fumble recovery in seven games as a safety last season.
"He's done an unbelievable job this offseason with his strength and conditioning training and with his summer training camp work," Withers said. "He will be a big part of our defensive plan going into the fall."
