The 49ers filled their vacant practice-squad spot with OLB Martail Burnett (Utah, 6-3, 262). He spent 20'08 season on Vikings' p-squad. He was recruited to college as a safety, then put on 50 pounds and played defensive end. He ranks in Utah's top 10 all-time with 17 sacks and 33.5 tackles for loss. Burnett takes the practice-squad spot that opened when the 49ers released WR Dobson Collins.
