Thirty-one NFL teams had until Friday at 9 p.m. PT to sign restricted free agent WR Danario Alexander to an offer sheet and submit it to the club. The deadline passed without word, a Chargers spokesman said Friday night, so it appears outside clubs can no longer negotiate with the 6-foot-5 target. Last year, Alexander joined the Chargers midseason. He caught 37 passes for 658 yards and seven touchdowns over the final nine games, which over a 16-game season projects to 66 receptions, 1,170 yards and 12 scores. The 24-year-old does have an extensive injury history that includes five surgeries to his left knee which may have been a factor in the teams' decision not to sign him to an aggressive offer sheet.
