‘Morrison will back up second-year pro Kelvin Sheppard at middle linebacker in Buffalo’s new 4-3, but he can also play outside. The 6-2, 245-pound product of San Diego State entered the NFL in 2005 as a third-round pick of the Oakland Raiders. He played the 2010 season for Jacksonville before joining the Bills as a free agent last summer. He saw action in 14 games with the Bills in a backup role. For his career, Morrison has 771 tackles, 6.0 sacks, seven interceptions and 18 passes defended.’
