ALLEN PARK, Mich. (AP) — Authorities say Detroit Lions receiver Nate Burleson broke his arm in a single-car accident early Tuesday after he reached over to keep two pizza boxes from falling off the front passenger seat.

Burleson's car hit a center median wall on a highway in suburban Detroit and he was taken to a hospital. Michigan State Police Lt. Mike Shaw said alcohol wasn't a factor in the crash at 2:25 a.m.

Coach Jim Schwartz stopped short of writing off the rest of Burleson's season, but surgery is scheduled for Wednesday.

Burleson has a team-high 19 catches and his 239 yards receiving trail only teammate Calvin Johnson this season.

UNDATED (AP) — Dallas defensive end Anthony Spencer will have season-ending surgery on his left knee and may have played his last game for the Cowboys.

Spencer's agent says doctors have a "good idea" what type of surgery but were still considering options. Cowboys owner Jerry Jones spoke earlier on his radio show, saying Spencer was likely to have microfracture surgery.

Spencer originally injured the knee in offseason workouts and aggravated it during the conditioning test the day before training camp.

The 29-year-old Spencer had arthroscopic surgery July 25 and missed the preseason and the opener against the Giants. He returned and played more than half the game in Week 2 against Kansas City before he was sidelined again.
