Slotback Ryan Grice-Mullins today will announce on his blog that he will forgo his senior season at the University of Hawai'i and apply for the National Football League draft in April.

But linebacker Adam Leonard has decided to remain at Manoa for his senior season.

According to televised reports, Grice-Mullins has signed with an agent, which makes him ineligible to play in an NCAA game next season.

Grice-Mullins did not return messages left on his cell phone. But he is expected to confirm on his blog, which can be found at www.hawaiiathletics.com.

Grice-Mullins' departure makes it a clean sweep of all four starting receivers and the No. 1 quarterback from UH's Sugar Bowl team. Quarterback Colt Brennan and wideouts Jason Rivers and C.J. Hawthorne finished their NCAA eligibility. Left slotback Davone Bess, who was a junior in 2007, has applied for the NFL draft.

Grice-Mullins led the Warriors in receiving yards (1,372) and receiving yards per game (105.5). He tied Rivers with a team-high 13 touchdown catches.

Grice-Mullins and Bess are training in Arizona.

Leonard, who was named to the 2007 All-Western Athletic Conference first team, finished with 105 tackles. He led the Warriors with four sacks and six quarterback hurries. In addition, he had 11.5 tackles for losses.

Leonard requested an assessment of his draft potential from a panel of NFL scouts. He declined to say which grade he received.

"I think I have more to prove," Leonard said. "I feel my best football is ahead of me."

Leonard played all of last season despite a fractured right thumb. A recent medical scan of his right thumb showed that a piece of bone broke off completely. He will undergo another scan today, at which time it will be decided if the injury requires surgery or will heal with rest.

He said he would miss only a month of weight-training if he undergoes surgery.

"Hopefully the scan can answer my questions," Leonard said.

He said he has fully recovered from last summer's knee surgery.
