Williams had been on scholarship last season, but as a sixth-year senior, Richt wasn't sure if one would be available for Williams again this season.
"It worked out it was available, and he deserved it," Richt said.
In addition to the scholarship, Boyd earned additional praise from Richt for his efforts at practice.
The senior is transitioning from linebacker to fullback this season, and got his first taste of action during Wednesday's practice.
"(He) kind of christened himself picking up a block at fullback, which was very nice," Richt said.
CAMP INJURIES: Freshman wide receiver A. J. Green was back in action Wednesday after missing practice the day before with a hip flexor injury. Richt said Green was not at full speed, but did participate in several drills.
"The more he learns and the healthier he gets, we'll get a chance to really see what he can do," Richt said of the highly touted Green. "But there's no reason to believe he's anything less than we expected."
"I think he lost 11 pounds after one practice, and he just didn't replenish quite as quick as you'd like, and he just was feeling bad," Richt said.
