The 49ers added former Charger Scott Tolzien, their opponent in Thursday's finale, to the active roster, according to Tolzien's agent, a move that prompted them to say goodbye to former Sacramento State quarterback McLeod Bethel-Thompson. Bethel-Thompson had been added to the practice squad earlier in the day, according to his agent, but became expendable when the team added Tolzien to the 53-man roster. Both are rookies. Tolzien (6-3, 205) completed 74.3% of his passes at Wisconsin last year, one of the best percentages in the nation, and he ranked fourth nationally in passer rating. However, he went undrafted in April. The 49ers were one of the teams that were interested in signing him as a free agent in July but he went to San Diego instead because the Chargers, unlike the 49ers, did not use a high draft pick on a quarterback.
