Eagles coach Chip Kelly might wait until Sunday before deciding on his starting quarterback for Philadelphia's game at Tampa Bay.
Michael Vick is nursing a pulled hamstring, suffered in last Sunday's 36-21 win over the New York Giants, and has been limited all week. Foles played well in relief of Vick as the Eagles improved to 2-3.
Foles worked with the first team again on Thursday.
"I get a feel from Mike that he is improving, and I just go day by day," Kelly said. "He said he felt good. But we'll see what happens when we go and get warmed up."
The Buccaneers (0-4) are coming off a bye week, and lost to the Eagles last season.
