BALTIMORE (AP) — The night was supposed to be about the long-awaited returns of quarterback Joe Flacco and linebacker Terrell Suggs. [...] Baltimore Ravens coach John Harbaugh ended up lamenting two significant injuries and a preseason schedule filled with games that are "not meaningful." Flacco went 11 for 16 for 94 yards in his first action since November, but the Ravens apparently lost tight end Benjamin Watson for the season during a 30-9 preseason victory over the Detroit Lions on Saturday night. After Watson tore his right Achilles tendon on the game's first play, promising rookie running back Kenneth Dixon left in the second quarter with a sprained knee. Harbaugh said the league's coaches don't need the games to get their teams prepared for the regular season. Underscoring the notion that results in the preseason mean nothing, Lions running back Ameer Abdullah said, "I'll start caring about winning when they keep score." Suggs, meanwhile, participated in his first game since tearing his Achilles tendon in the season opener last year. With Watson out, Flacco turned his attention toward wide receiver Mike Wallace, signed as a free agent during the offseason. Standout defensive end Haloti Ngata faced the Ravens for the first time since being traded from Baltimore to Detroit last season.
