Veteran acquisition Darnell Dockett continue to be No. 90 in his first season with the 49ers, and Glenn Dorsey will have to find another number to wear.
Dockett wore No. 90 during his 10 seasons as a defensive tackle with the Arizona Cardinals after breaking into the NFL in 2004. Dorsey was assigned No. 90 when he came to the 49ers as a free agent prior to the 2013 season. It is not known what agreement Dockett reached with Dorsey to assume the number.
Dorsey had previously worn No. 72 at LSU and in his first five seasons with the Kansas City Chiefs.
