The Cavs, off to their best start since 1998, lead the Atlantic Coast Conference in total offense (493.2 yards per game), rushing offense (275), passing offense (218.2) and scoring (42.4).
One key to Virginia's early success is a lack of turnovers -- the Cavs have committed just two turnovers, tied for second fewest in the country.
While Bunkley doesn't expect to be 100 percent for the game after suffering a left ankle sprain against North Carolina on Oct. 2, he is determined to help make a difference for the Seminoles.
Bunkley did not play in FSU's win at Syracuse last Saturday.
"I am going to try to play at 100 percent -- it's bugging me a little bit but hopefully as the week goes on, it will improve," said Bunkley, a bag of ice wrapped around his left ankle.
Bunkley spent a majority of Tuesday's practice working on his conditioning, including dragging a weight plate across the field.
"Hopefully my adrenaline for the game takes me the rest of the way," Bunkley said.
Bunkley and the Seminoles' defense must contend with a potent UVa running game.
The Cavs have rushed for at least 225 yards in every game this season after rushing for more than 200 yards just three times in 13 games last year.
All five of this season's performances rank in the top-seven under UVa coach Al Groh.
UVa tailback Wali Lundy is fourth in the ACC in rushing with an average of 96.8 yards per game.
The junior also is tied for the lead in the nation in rushing touchdowns (10) and is tied for fourth nationally in total touchdowns (10). Overall, he has scored 15 touchdowns in the last seven games going back to last season.
Lundy has teamed with Alvin Pearman to give the Cavs a potent one-two punch in the backfield.
Pearman currently leads the ACC in all-purpose yardage with an average of 136.8 yards per game. He was the only player ranked in the ACC's top 10 in rushing (eighth) and receiving (seventh) last season.
It's easy to see why Bunkley wants to be as healthy as possible for Saturday.
"It's still sore when you try to run with a full stride -- you still have to go on your heel a little bit," Bunkley said. "But it's a major improvement from last week.
"I am just going to try to go out there with a well-taped ankle and hopefully nothing serious happens or it doesn't bother me that much. If it doesn't bother me much, I will be fine."
