"Shoot, I thought I had blown out everything," Henshaw said following the team's Tuesday practice.
"When it first happened, I knew I got rolled up. But, I mean, I felt my ankle just pop, crackle and snap -- every sound you can think of. That was the worst pain I ever felt in my life.
"I went and looked at it on film, it was nasty."
Following the injury, Henshaw, wearing a protective boot and on crutches, was taken into the locker room for X-rays.
Henshaw's father was so concerned he telephoned his son, fearing he had suffered a knee injury.
"After I had X-rays, I talked to my dad and he asked me how my knee was," Henshaw said.
"I told him it wasn't my knee. He thought I had blown out my knee. Thankfully, it's a foot (ankle sprain)and I thank the Good Lord for that. It's not as bad as I thought it would be."
Henshaw, who is still wearing a protective boot on his right foot, is hopeful he can play in Saturday's Atlantic Coast Conference showdown against sixth-ranked Virginia on Saturday.
Henshaw plans to test his ankle in practice today.
"Actually, I am going to see what I can do on it (today) and hopefully on Thursday I can go in the walk through," Henshaw said.
"If I can, hopefully Randy (Oravetz, FSU head trainer)will let me play. If not, then I can't play -- it's plain and simple."
FSU coach Bobby Bowden said on Tuesday that tackle Mario Henderson also will be available at tight end if needed.
Henshaw says he has plenty of confidence in Irons and Root.
"They can handle it. They are very capable of handling it - and did against Syracuse," Henshaw said.
"Paul did get 50-something snaps, which is a heckuva a lot of snaps for one guy to take, especially after he's used to taking maybe 20 or 30 with Matt and I in the rotation. But they can handle it."
