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.”
