Matthew Stafford wouldn't comment on the health of his throwing arm Wednesday, but the Detroit Lions quarterback gave the impression he was fine. The Lions injury report also hinted Stafford would be good to go for Sunday's visit to TCF Bank Stadium, noting he was healthy enough for full practice on Wednesday.

Stafford took a big hit early in the second half of Sunday's 33-28 loss to San Diego and was seen wearing a large wrap on his throwing arm on Monday. The Detroit Free Press reported Wednesday that he swapped the wrap for the same arm sleeve he wore Sunday after being hit by Chargers linebacker Melvin Ingram.

Stafford was intercepted on the play and threw his second pick of the day two attempts later. He was nearly picked off again on the Lions' final drive, but replays overturned the call. The Lions quarterback, who threw just 12 interceptions all last season, said the big hit didn't affect his accuracy throughout the second half.

"It didn't [have an impact]," Stafford said via telephone. "One was a poor decision, obviously, and the other was a heck of a play by another guy and unfortunately we got hit."

Asked if his quarterback was healthy, Lions coach Jim Caldwell only said, "He's OK."

Caldwell can't say the same for several of his other important pieces. Linebacker DeAndre Levy (hip), defensive tackle Haloti Ngata (shoulder), tight end Brandon Pettigrew (hamstring) and wide receiver Golden Tate (quad) did not practice.

The Lions scored 21 points in 21 minutes on Sunday before being held scoreless for the next 37. Caldwell didn't like his team's all-around effort, but Stafford liked the fast start.

"Any time you play on the road you want to have a good start, so we were fortunate to do that, but we didn't finish it the way we wanted to," Stafford said. "We understand that we've got some mistakes on tape that we have to fix. … It's stuff we know how to do. We just didn't execute well enough. That was everybody – offense, defense, special teams. We just gotta find a way to correct those mistakes and move forward."
