Sexton came off the bench to rally the Seminoles past Clemson last weekend when Rix went out late in the first quarter.
Stovall, meanwhile, had a big game against the Tigers, finishing with a career-high seven catches for 96 yards and the team's first touchdown reception of the season -- 47 yards from Sexton.
"To me it is the same old, same old. That's what practice is for," Stovall said.
"We are going to get better and better as we play more together. We are just trying to keep him focused. I talk to him in practice and let him know what he is going to get into and what is coming ahead."
Stovall said it's important that FSU's offensive players help Sexton with the transition from backup to starter. Rix is expected to miss at least two weeks, which would include a trip to Syracuse next weekend.
FSU is at home in a key Atlantic Coast Confernce showdown against Virginia on Oct. 16.
"He knows the offense pretty well," Stovall said of Sexton.
"There are a couple things that we threw at him that were new and he slipped up on, but that's what practice is for and he has figured them out and we are going to go with it."
Stovall is looking to build on his performance against the Tar Heels.
Stovall's 11 receptions this season is second to fellow receiver Craphonso Thorpe (12). He is averaging 14.8 yards per catch and a team-high 54.3 yards per game.
Stovall, for one, is sorry to see the Clemson Tigers leave. He has 11 catches for 227 yards and two touchdowns in two games against the Tigers.
