Burgess did not report for the start of Patriots training camp Thursday at Gillette Stadium. The odd development comes after the 31-year-old Burgess chose to re-sign with the Patriots in June. His one-year contract has a $1.4 million base salary and included a $100,000 signing bonus.
If Burgess decides to quit, his absence would weaken an already uncertain outside linebacking corps. The Patriots ranked 22nd in sacks last year with 31. Burgess was tied for second on the team with five sacks.
Burgess played all 17 games. He started four games at outside linebacker and two at defensive end.
