Houston signed center Ben Jones, receiver Keshawn Martin and defensive end Jared Crick, all fourth-rounders, kicker Randy Bullock (fifth round) and tackle Nick Mondek. The Texans also announced the signings of 21 undrafted free agents on Monday. One of them is quarterback Case Keenum, who became the career leader in yards passing (19,217) and touchdown passes (150) at Houston.
The 6-foot-3, 303-pound Jones, the 99th overall pick out of Georgia, will back up Chris Myers, who made the Pro Bowl last season. The 5-11, 194-pound Martin made 127 receptions for 1,714 yards at Michigan State. The 6-4, 276-pound Crick started his final 33 games for Nebraska, and his 20 sacks ranked eighth on the school's career list.
