ALLEN PARK -- Detroit Lions head coach Jim Caldwell said Tuesday that no decision has been made yet as to whether starting quarterback Matthew Stafford will play Thursday night in the team's final preseason game at Buffalo.

He said no blanket decision has been made in regards to the Lions' starters.

"That remains to be seen," Caldwell said. "We haven't made a declaration yet of who will play. It's not going to be across the board decision with any particular position or individual."

Caldwell says the main factor in deciding who will play and who won't will be based on whether the coaching staff feels it "needs to see" a guy play.

So far this preseason, Stafford has gone 21 of 30 for 204 yards, two touchdowns and one interception. Thursday against the Bills will be the final opportunity for live action before Week 1's Monday Night Football showdown with the New York Giants on Sept. 8.

Stafford was pleased with the protections he got from the offensive line last week against Jacksonville, and noted Reggie Bush's brilliant 86-yard touchdown run in the first quarter. But that would prove to be the lone score from the starting offense, despite playing into the third quarter.

Stafford completed one of his first five passes. Two of those incompletions were nearly intercepted, and a third one was by defensive end Andre Branch.

Most of the attention Thursday will be paid to those still trying to make the roster before the Lions cut their roster to 53 players. With that in mind, Caldwell expects the majority of snaps to go to the reserves.

"This game is really important to a lot of guys and particularly those that are in tight battles," Caldwell said. "These games count heavily for those individuals that are playing in the games and a lot of them will get a little bit more playing time. Some maybe haven't gotten any playing time to this point. They try to take advantage of it."
