"I've been able to get some endurance in my knee," Washington said.
"When I started it out, I was over-working it and it started getting a little sore. Right now I am trying to back it off of it a little bit. Take it easy until I get used to it. But it's not swelling. It's only a matter of soreness.
"I will be right for two-a-days if the Lord is willing."
Washington is a big, physical fullback who had 1,161 rushing yards and 21 touchdowns during his senior season at Madison County High School. Slowed by a knee injury last season, Washington is looking to make up for lost time.
For the first time in two years, the Seminoles should have three healthy fullbacks ready for two-a-day practices -- Washington, B.J. Dean and James Coleman all are participating in voluntary workouts.
"We have the talent to do big things this year. We just have to go at it the right way," Washington said.
"I think the most important thing is our attitude. It all depends on the players. If the players want it, then it's about how we go out and play. I am excited and looking forward to the season. I've had a good summer."
Coleman, who missed spring practice after undergoing surgery to repair a torn labrum (cartilage) in his shoulder, is expected to be cleared soon by team doctors.
Dean, meanwhile, has added noticeable bulk to his upper body and is tipping the scales around 245 pounds.
